For the given coordinates (-4,-3) and (7,1) , the slope of line is 4/11.
How is slope determined?Determine the coordinates of two locations along the line that you choose.
Find the difference between these two locations' y-coordinates (rise). Find the difference between these two locations' x-coordinates (run). Divide the difference in x-coordinates (rise/run or slope) by the difference in y-coordinates.
Given, the points are -
(-4,-3) and (7,1)
The formula to calculate slope is -
m = y2 - y1 / x2 - x1
Putting the value in the formula,
m = 1 +3 / 7 + 4

Distance between (0,0) to (2,5)
The distance between (0,0) and (2,5) is √29.
Given,
(0,0) to (2,5)
We need to find the distance between (0,0) and (2,5).
What is the distance formula between two points?It is given as:
If two points are (a,b) and (c,d)
d = √ ( c - a )²+ (d - b )²
Find the distance between (0,0) and (2,5).
We have,
d = √ ( 2 - 0 )² + ( 5 - 0 )²
d = √ 2² + 5²
d = √ 4 + 25
d = √ 29
Thus the distance between (0,0) and (2,5) is √29.

y varies directly with x .
If y=4 when x=-2 , find x when y=6 .
Using direct variation, As y varies directly with x, for y=6 the value of x will be -3.
What is direct variation?Direct variation is the change in one quantity as a result of the change in another. This suggests that if one quantity rises or falls, the other must rise or fall correspondingly as well.
As y varies directly with x,
Using direct variation,
⇒ y = kx
⇒ 4 = k (-2)
⇒ k = -2
⇒ For y = 6,
⇒ x = y / k
⇒ x = 6 / -2

Hey Siri Rhea couple by basic car cost in $26, 500,000 with options costing 725,000
Ray's total cost was $28, 908.50
Ray Cupple bought a basic car costing at $26,500.00,
The options costing is $725.00.
The sales tax in the state is 6%
The combined cost for license and registration fee is $50.00
Cost price of car = $26,500 and the Cost of options= $725
Therefore, the total taxable cost=$26,500+ $725=$27225
Tax amount = 6% of Total taxable cost
=0.06 x $27225 = $1,633.5
Total cost = $27225 + $1,633.5 + $50
Total cost = $28,908.50

In this problem, you will investigate the relationship between same-side exterior angles.
c. Make a conjecture about the relationship between the pair of angles formed on the exterior of parallel lines and on the same side of the transversal.
The relationship between the angles formed on the exterior of parallel lines on the same side is Co-Exterior Angles
In the picture mentioned, there are two lines m and n parallel to each other and a transversal t. It forms exterior angles on the same side of the transversal as highlighted. According to the property of Co-exterior angles,
=> ∠1 ≅ ∠8
=> ∠2 ≅ ∠7
When a transversal is constructed on parallel lines, there are angles formed on both interior and exterior sides of the parallel lines. The pair of angles formed on the exterior side of parallel lines which are on the same side of the transversal dropped on the parallel lines are called Co-exterior angles. These angles formed are congruent to each other.

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

Are the two lines parallel and why?
The graph has two lines and the lines are parallel lines.
Given that,
There is graph in the picture with 2 lines and 4 points.
The points are A=(0,6) and B=(8,0) of line 1.
The points are C=(-3,4) and D=(0,2) of line 2.
From the line 1 points A and B we can find the equation by using the slope equation formula.
Let take A=(0,6)=[tex](x_{1} ,y_{1} )[/tex] and B=(8,0)=[tex](x_{2} ,y_{2} )[/tex]
slope m= [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} } =\frac{0-6}{8-0}=\frac{-6}{8}=\frac{-3}{4}[/tex]
Now, To find the equation of the line the formula is
[tex]\frac{y -y_{1} }{y_{2} -y_{1} } =\frac{x -x_{1} }{x_{2} -x_{1} }\\\frac{y -6}{0 -6 } =\frac{x -0 }{8 -0 }\\\frac{y-6}{-6}=\frac{x}{8}\\ 8(y-6)=x(-6)\\ 8y-48=-6x\\6x+8y-48=0[/tex]
Therefore, the 1st line equation is [tex]6x+8y-48=0[/tex]
Let take C=(-3,4)=[tex](x_{1} ,y_{1} )[/tex] and D=(0,2)=[tex](x_{2} ,y_{2} )[/tex]
slope m= [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} } =\frac{2-4}{0-(-3)}=\frac{-2}{3}[/tex]
Now, To find the equation of the line the formula is
[tex]\frac{y -y_{1} }{y_{2} -y_{1} } =\frac{x -x_{1} }{x_{2} -x_{1} }\\\frac{y -4}{2 -4 } =\frac{x -0 }{-3 -0 }\\\frac{y-4}{-2}=\frac{x}{-3}\\ -3(y-4)=x(-2)\\ -3y+12=-2x\\2x-3y+12=0[/tex]
Therefore, the 2st line equation is [tex]2x-3y+12=0[/tex].
So, from the 2 equation we have
6x+8y-48=0 and 2x-3y+12=0.
[tex]a_{1} =6,b_{1} =8,c_{1} =48[/tex]
[tex]a_{2} =2,b_{2} =-3,c_{2} =12[/tex]
We have to check weather it satisfy the condition or not.
[tex]\frac{6}{2}\neq\frac{8}{-3} \\\frac{a_{1} }{a_{2} }\neq\frac{b_{1} }{b_{2} }[/tex]
Therefore, it satisfy the condition so the lines are parallel lines.

What is equation of a line?The equation of a line is a form of representing the set of points, which form a line in a coordinate system.
The general equation of a straight line is given as:
y = mx + c,
where m = slope of the line and c = y-intercept.
We have,
Two points:
(1, -4) = (a, b) and (2, -1) = (c, d)
The equation of a line can be written in the form:
y = mx + c
Slope:
m = (d - b) / (c - a) = -1 + 4 / 2 - 1 = 3 / 1 = 3
y-intercept:
Take a point (1, -4).
-4 = 3x1 + c
-4 - 3 = c
c = -7
