Question

Find the slope of a line perpendicular to y=⅖x+⅘
​

Answer 1

-2.5

Explanation:

The perpendicular slope will be the opposite reciprocal of the original slope.
So the slope of the perpendicular will be:

`(-1)/(0.4)` = -2.5

If we were asked to give the equation of the perpendicular it would be:

-2.5x+ 4/5

Answer 2

To find the slope perpendicular we will take our original slope (2/5) and find the reciprocal.
To do this, we will flip the slope (so we get 5/2) and make it negative so we get our final perpendicular slope of -5/2
