Y - 3x = -8 y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b slope(m) = -1/3 (3,2)...x = 3 and y = 2 now we sub and find b, the y int 2 = -1/3(3) + b 2 = -1 + b 2 + 1 = b 3 = b
