A line has a y-intercept of 8 and a slope of 4. What is its equation in slope-intercept form?

Answers

Answer 1

Answer:

y = 4x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = 8 , thus

y = 4x + 8 ← equation of line

Answer 2

The equation in slope-intercept form is y = 4x+8

What is the equation of a line?

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

Given that, a line has a y-intercept of 8 and a slope of 4.

We know that, the general equation of a line is given by, y = mx+c

where m is slope and c is the y intercept,

Here, m = 4 and c = 8

Therefore, the equation can be, y = 4x+8

Hence, The equation in slope-intercept form is y = 4x+8

Brad and Stella volunteer to help at the party. Brad volunteers at the prize table and Stella

different intervals. The prize table allows volunteers a short break every 20 minutes, but the
refreshment table allows a short break only every 30 minutes. If the party is scheduled to start
at 2:00 pm and Brad and Stella both start working then, what is the first time that they will be

Answer:

They will be able to have their break together in 60 minutes.

Step-by-step explanation:

You will have to find the least common multiple (LCM) between 20 and 30.

The prime factorization of 20 is: 2 x 2 x 5

The prime factorization of 30 is: 2 x 3 x 5

Eliminate the duplicate factors of the two lists, then multiply them once with the remaining factors of the lists to get lcm(20,20) = 60

The coordinates of the midpoint of line GH are M(−132,−6) and the coordinates of one endpoint are G(−4, 1). The coordinates of the other endpoint are

The coordinates of endpoint G are (-4,1)

The greatest common factor is 7.

Factor 7 out and divide the terms by 7:

Answers

Answer:

The correct answer is x = 17.

Step-by-step explanation:

If EF bisects DEG, this means that angles DEF and angles FEG are congruent, and they each make up half of angle DEG.

Therefore, we can set up the equation:

DEF + FEG = DEG

However, since we know that DEF and FEG represent the same value, we can change this equation into the following:

2(DEF) = DEG

Now, we can substitute in the expressions that we are given:

2(3x+1) = 5x + 19

To simplify, we should first use the distributive property on the left side of the equation.

6x + 2 = 5x + 19

Our next step is to subtract 5x from both sides of the equation.

x + 2 = 19

Finally, we can subtract 2 from both sides of the equation to get x by itself on the left side.

x = 17

Therefore, the value of x is 17.
