Question

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of −2? y = x +

Answer 1

y = -2x+28

Explanation:

We have the slope and a point, so we can use the point slope form to make a line

y-y1 = m(x-x1)

y-12 = -2(x-8)

Distribute the -2

y-12 = -2x+16

Add 12 to each side

y-12+12 = -2x+16+12

y = -2x+28

This is the slope intercept form of the line
