Find the slope of a line perpendicular to each given line.

A

Step-by-step explanation:

The slope of the line you are given is -10/3 (since it is m in the y=Mx+b, where m is the slope)

To find the slope of a line perpendicular to that, you would multiply the given slope, -10/3 by negative.

-(-10/3) gives you 10/3.

But it doesn’t end here. You have to now find the reciprocal of 10/3. Essentially you are finding the negative reciprocal of the slope you are given to get the slope of the perpendicular line.

The reciprocal of 10/3 is 3/10. So there you go, your answer is 10/3, which is A.
