Question

Write an equation so y is a function of x: 8x - 2y = 16

Answer 1

The goal is to solve for y. To do so, you subtract 8x from both sides. Then you divide both sides by -2 to fully isolate y.


\[\Large 8x - 2y = 16\]


\[\Large -2y = 16-8x\]


\[\Large -2y = -8x+16\]


\[\Large y = \frac{-8x+16}{-2}\]


\[\Large y = \frac{-8x}{-2}+\frac{16}{-2}\]


\[\Large y = 4x-8\]
