Answer:
1/3
Step-by-step explanation:
y = −3x −2
This is in the form y = mx+b where m is the slope
This line has a slope of -3
We want the slope of a line that is perpendicular
Lines that are perpendicular have slopes that are negative reciprocals
m = -(1/-3)
m = + 1/3
The slope of a line that is perpendicular is 1/3
