Question

What is the equation?

Answer 1

C

Explanation:

Put it into slope form

y=mx+b

distribute the -3 from (y+1) = -3 (x-1)

y+1 = -3x +3

subtract the 1

y=-3x +2

Answer 2

y+2 = -3(x-1)

Explanation:

We take 2 points and we can find the slope

(0,2) and (2,-4)

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

= (-4-2)/(2-0)

= -6/2

= -3

The slope is -3

We can use point slope form to make an equation. We want to use the point (1, -2)

y-y1 = m(x-x1)

y--2 = -3( x-1)

y+2 = -3(x-1)
