Question

Y-(-4) =m(x-(-5)) solve for m

Answer 1

m=y+4x/x+5 your welcome !!

Answer 2

m =
`(y+4)/(x+5)`

Explanation:

y-(-4) = m(x-(-5))

Simplify, distribute the negative sign outside of the parenthesis, remember negative times negative equals positive

y + 4 = m (x + 5)

Inverse operations, divide the equation by the value inside of the parenthesis

`(y+4)/(x+5)` = m
