Best ResponseYou've already chosen the best response.1\[y(7)=\frac{16}{9}(x3)\] \[y+7=\frac{16}{9}x+\frac{16}{3}\] \[y=\frac{16}{9}x\frac{5}{3}\]

Best ResponseYou've already chosen the best response.0no, if you minus 7, u have to minus it from both sides

Best ResponseYou've already chosen the best response.1\[y=\frac{16}{9}x\frac{5}{3}\] Multiply both sides by 9 to clear the fractions

Best ResponseYou've already chosen the best response.0so u use point slope form to find b, then rearange to fit Ax+By=c?

Mertsj
