Question

What is the equation of the line that passes through the point (-3,6) and has a slope of -2?

Answer 1

Explanation:

y - 6 = -2(x + 3)

y - 6 = -2x - 6

y = -2x

Answer 2

y = -2x

Explanation:

The equation of a line in point slope form is

y-y1 = m(x-x1)

Where m is the slope and (x1,y1) is a point on the line

y - 6 = -2(x- -3)

y - 6 = -2(x+3)

Distribute

y-6 = -2x-6

Add 6 to each side

y-6+6 = -2x-6+6

y = -2x
