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
