Question

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

Answer 1

`1/5`

Explanation:

A straight line in slope and intercept form is: `y=mx+c`
Where `m` is the slope and `c` is the intercept on the `y`-axis

For two lines to be perpendicular to one another the product of their slopes must `=-1`

In this example: `y=-5x+2 -> m=-5`

Hence the slope of the line perpendicular `= (-1)/-5 = 1/5`
