Answer:
y = -1/3x + 5
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes, so the slope of the line will be -1/3
Plug in the slope and given point into y = mx + b to solve for b
y = mx + b
6 = -1/3(-3) + b
6 = 1 + b
5 = b
Plug in the slope and b into y = mx + b
y = -1/3x + 5 is the equation of the line
