the graph of f passes through (-9,7) and is perpendicular to the line that has an x-intercept of 6 and a y-intercept of -18



Answer :

Answer:

We are looking for an equation of a line that is perpendicular to the line y = 3x - 18.

y - 7 = (-1/3)(x + 9)

y - 7 = (-1/3)x - 3

y = (-1/3)x + 4

3y = -x + 12

x + 3y = 12
