How do you graph an equation using x and y intercepts.

Answers

Answer 1

Answer:

I'm going to use the following as an example.

[tex]2x + 4y = 8[/tex]

To find the y-intercept, set x equal to 0 then solve for y.

[tex]2(0) + 4y = 8[/tex]

two times zero is zero, so we have the following equation.

[tex]4y = 8[/tex]

Solve for y

[tex] \frac{4y}{4} = \frac{8}{4} \\ y = 2[/tex]

Your first point you will graph is (0, 2).

Now solve for the x intercept. To do this, set y = 0.

[tex]2x + 4(0) = 8[/tex]

4(0) = 0, so you can remove it, and solve for x.

[tex]2x = 8[/tex]

[tex] \frac{2x}{2} = \frac{8}{2} \\ x = 4[/tex]

Now the next point you have is (4, 0). plot that point. Connect the two points with a line and you are done.

In mathematics, the vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x.

any vertical line in the plane can intersect the graph of a function at most once.

HOW TO DO THIS

take your pencil and place it on your paper vertically (up and down direction)

move the pencil across the paper to the right

if the pencil crosses more than two points on the line it is not a function

the first problem would be a function

the second problem would be a function

the third problem would not be a function

No, The segments shown below could not form a triangle.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Three line segment with measure 9 , 4 and 15 are shown.

We know that;

The sum of two sides of a triangle are always greater than the third side,

Here, 9 + 4 = 13 < 15

Hence, The segments shown below could not form a triangle.

Thus, The segments shown below could not form a triangle.

Answer:

C. (2,7)

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

In order to find which ordered pair makes the equation true, we have to understand that the format of a coordinate pair is (x, y)

Knowing that, we can plug in the numbers from each coordinate pair that correspond to the x and y values of the equation

For instance, for A (-1, 5) we would plug in 5 for x and -1 for y

Now we have -1 = 3(5) + 1

Multiply 3 and 5

-1 = 15 +1

Add

-1 = 16

The numbers on each side are not equal so this is not the answer

Now for B (10,3)

We do the same thing, plug in the numbers

3 = 3(10) + 1

Multiply

3 = 30+1

3 = 31

This choice is false as well

Option C (2, 7)

Plug in the numbers

7 = 3(2) + 1

Multiply

7 = 6+1

Add

7 =  7

Thus C is the answer as it is the same number on both sides~!

The y-intercept is 4.

Step-by-step explanation:

Our equation: y = mx + b

m = slope

b = y-intercept

We can tell that b = 4

A path is made of red tiles and blue tiles.
1/5of the tiles are red.
a) Write down the ratio of red tiles to blue tiles in its simplest form.

There is a total of 85 tiles.
b) Work out the number of blue tiles.
(2)
Total marks: 3

Answers

Answer: 17 red , 68 blue

Step-by-step explanation:

85 divided by 5=17

1/5 of 85=17

17x4=68

4/5 of 85=68

(1). The ratio of red tiles to blue tiles is [tex]\frac{1}{4}[/tex]

(2). The number of blue tiles are 68.

Fraction:

It is given that,

A path is made by red and blue tiles and [tex]\frac{1}{5}[/tex] part of tiles are red.

So that,

 Blue tiles[tex]=1-\frac{1}{5} =\frac{4}{5}[/tex] parts.

The ratio of red tiles to blue tiles in its simplest form,

                [tex]\frac{Red}{Blue}=\frac{1}{5}*\frac{5}{4} \\\\\frac{Red}{Blue}=\frac{1}{4}[/tex]

Since, total number of tiles are 85.

 Number of blue tiles[tex]=\frac{4}{5} *85=68[/tex]
