Question

70. Write the standard form of the equation of the line with

slope -2 passing through the point (-2,-4).

Answer 1

Explanation:

y-y1=m(x-x1)

y+4=-2(x+2)

y+4=-2x-4

2x+y+8=0

or 2x+y=-8

Answer 2

y = -2x - 8

Explanation:

Use the point slope form: (y - y1) = m(x - x1)

(y - (-4)) = -2(x - (-2))

y + 4 = -2(x + 2)

y + 4 - 4 = -2x - 4 - 4

y = -2x - 8

Answer: y = -2x - 8
