Question

Write the equation of a line that is perpendicular to the given line and that passes through the given point.

-3x - 6y = 17; (6,3)

A) y = -2x - 9
B) y = 1/2x + 0
C) y = 2x - 9
D) y = 1/2x - 9

Answer 1

-3x - 6y = 17

-3x - 17 = 6y

y = -3/6*x - 17/6 = -1/2*x - 17/6

y = 2 * (x - 6) + 3 = 2x - 12 + 3 = 2x - 9
