Question

 Which of the following is an 

equation of the line that passes through the point (-2, 3) and is perpendicular to the graph of the equation y = 3x – 2?

Answer 1

Then the perpendicular line has slope -1/3

B = y - mx = 3 - (-1/3)(-2) = 3 - 2/3 = 9/3 - 2/3 = 7/3

The equation is (-1/3)x + 7/3
