Question

Choose the equation below that represents the line that passes through the point (7,-2) and has a slope of -3.

A.) y - 2 = -3(x+7)
B.) y + 7 = -3 (x-2)
C.) y + 2 = -3 (x-7)
D.) y - 7 = -3 (x+2)

Answer 1

Hi,

y-y₀ = m(x-x₀)

For (x₀,y₀) = (7,-2) and m = -3

y-(-2) = -3(x-7)
y+2 = -3(x-7)

Answer:

C. y+2 = -3(x-7)
