Question

How do you find the slope that is perpendicular to the line `5x-2y=-1`?

Answer 1

`=-2/5`

Explanation:

`5x-2y=-1`
or
`2y=5x+1`
or
`y=5/2x+1/2`
`y=mx+c` where `m` is the slope
Slope=`5/2`

But slope of the line that is perpendicular to the above line`=-1/m`
Hence
slope of the line that is perpendicular to the above line`=-2/5`
