Question

Find the equation of the line passing through the point (–1, 5) and perpendicular to the line y = – 3x + 4. answers : A) 3y = x + 16 B) 3y = –x + 16 C) y = –3x + 2 D) y = –3x + 8

Answer 1

3y=x+16

Explanation:

If you plot the gradient must be 1/3 since its perpendicular. Only the option has the gradient as 1/3.

Answer 2

C) y= -3x+2

Explanation:
