BartSMP [9]

Answer:

The answer to your question is:      y = -3x + 14

Step-by-step explanation:

Data

A (4, 2)

y = x/3  - 1

Perpendicular

original slope = 1/3

perpendicular slope = -3

Equation                 (y - y1) = m(x - x1)

                               (y - 2) = -3(x - 4)

                               y - 2 = -3x + 12

                               y = -3x + 12 + 2

                               y = -3x + 14
