What is the slope of a line that is perpendicular to the line y=-3x+5? A.-2
B.-1/2
C.1/2
D.2

Step-by-step explanation:

Note: there is a typo in the question, the line should be y = - 2x + 5

Perpendicular lines have negative reciprocal slopes

Slope of the given line is:

The slope of a perpendicular line is:

Correct choice is C. 1/2

m=−3

The equation of a perpendicular line to y=−3x+5

must have a slope that is the negative reciprocal of the original slope.

m perpendicular =−1/−3

Simplify the result.

m perpendicular =1/3

Hope this helps
