Question

How do you find the slope of a line perpendicular to the line `3x - y = 8`?

Answer 1

For any line with a slope of `m`
all lines perpendicular to it have a slope of `(-1/m)`

`3x-y=8`
can be written as
`color(white)("XXXX")` `y = 3x-8` which is the slope intercept form, with a slope of `3`

Any line perpendicular to `3x-y=8` will have a slope of `(-1/3)`
