What is the equation of a line that goes through these points? x -2, -1, 0, 1, 2 and y-1, 1, 3, 5, 7

Slope-intercept form is:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

You need to find "m" and "b"

To find the slope, you use the slope formula, and plug in 2 points. I will use the points (0,3) and (1,5):

m = 2

y = 2x + b

To find "b" you can plug in a point into the equation, or you can find the point when x = 0. When x = 0, the y value is 3, so the y-intercept is 3

y = 2x + 3

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
