Question

Find the equation of the line with slope m=−12 that contains the point (2,−4).

Answer 1

y + 4 = -12(x - 2)

Explanation:

Use the point-slope formula for the equation of a straight line:

y - k = m(x - h)

Here m = -12, h = 2 and k = -4, and so we have:

y + 4 = -12(x - 2)

Answer 2

y=-12x+20

Explanation:

-4=-12(2) +b

-4=24+b

(add 24 both sides)

20=b

slope: -12

y intercept: (0,20)
