Question

Choose the equation of the line passing through the point (-1, -2) and perpendicular to y = x + 2.

A) y = 4x - 6

B) y = -4x - 6

C) y = -4x + 2

D) y = 4x

Answer 1

since the line is perpendicular to the give line therefore slope of required line will be negative of inverse of given line's slope that is -1 now your equation of required line is y=-1*x+d...to find d substitute the given points (-1,-2)..you'll get d

Answer 2

Okay thank you:) !!! @ghazi

Answer 3

or else you can write equation directly as y-(-2)= -1(x-(-1))
