Question

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

7) y = 5/2x - 3

Answer 1

Answer:y= -2/5x-3

Explanation:

It's actually pretty simple, all you gotta do is flip the fraction around so if it is 5/2x now is 2/5, and then change the sign, since it was positive now it's negative

Answer 2

Slope: -2/5

Explanation:

If two lines are perpendicular to each other, their slopes are opposite reciprocals.

To get the opposite reciprocal of a number, change its sign, and flop it over.

Let's try it with 5/2, the slope of y = 5/2x - 3.

Change the sign:

-5/2

Flop it over:

-2/5

Therefore, the slope is -2/5.
