Question

Rewrite the equation in standard form : y=2x=7

Answer 1

2x - y = -7

Explanation:

The equation y = 2x+7 needs to be written in standard form
`Ax+By=C` where A must be positive.

To convert to standard form, subtract 2x from both sides.

-2x + y = 7

Multiply each term by -1.

-1(-2x + y =7)

2x - y = -7
