Question

Which of the following slopes would be perpendicular to the line y= -3/5 x +1

Answer 1

Perpendicular slopes are negative reciprocals of each other.

This means that if m1 is the slope of a line y and m2 is the slope of a perpendicular line to line y, we will have the following equality:

`m_1=-(1)/(m_2)`

Then, if the slope of the original line is m=-3/5, the slope of the perpendicular line will be:

`m_p=-(1)/(m)=-(1)/(-(3)/(5))=(5)/(3)`

Answer: The slope of the perpendicular line will be mp=5/3.
