What is the equation of the line that passes thru (1/2, -1/2) and (1/9, 3/9)?

I keep on messing up w/ the complex fractions.

ok

slope: (-9/18 - 6/18)/

9/18-2/18

=(-15/18)/ (7/18)

this is where i get stuck

how do i simplify these so i can substitute them into slope intercept form

(-15/18) / (7/18) = (-15/18) * (18/7)
