Question

m=8/9; (8,-9)

equation ?

Answer 1

\[\Large y = mx+b\]


\[\Large -9 = \left(\frac{8}{9}\right)\left(8\right)+b\]


\[\Large -9 = \frac{64}{9}+b\]


\[\Large -9-\frac{64}{9} = b\]


\[\Large \frac{-145}{9} = b\]


\[\Large b = \frac{-145}{9}\]


So the equation of the line is \[\Large y = \frac{8}{9}x-\frac{145}{9}\]
