Question

How do you find the slope perpendicular to `5x+2y=10`?

Answer 1

The slope of the perpendicular line is `=2/5`

Explanation:

Given -

`5x+2y=10`

Slope of the given line is `m_1=-a/b=-5/2`

Two lines are perpendicular when `m_1 xx m_2=-1`

Then

`m_2=-1/m_1=-1-:-5/2=-1xx-2/5=2/5`

`m_2=2/5`
