Line ab goes through the points (0,-4) and b (6,2). which equation represents line ab?

The answer is y = x - 4. The points already have the y-intercept which is -4, and to solve for the slope you must do 6-0 divided by 2 - (-4) which is equal to 6/6 which is equal to 1.

i would have to say it is c.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
