Type the correct equation of the line. (0, 1), (2, -3), (4, -7)

Explanation:

Use the slope formula to get the slope

m = (y2-y1)/(x2-x1)

m = (-3-1)/(2-0) .. I used the first two points

m = -4/2

m = -2

The slope is m = -2

The y intercept is b = 1 as this is the y coordinate of the point (0,1). The y intercept always happens when x = 0.

Plug the m and b value into y = mx+b to get y = -2x+1

As a check, plug x = 0 into y = -2x+1. You should get y = 1.

Repeat for x = 2 and you should get y = -3

Repeat for x = 4 and you should get y = -7
