Question

What is y−4=−2(x+7) written in standard form?

Answer 1

Y=2x+18

Hope that helps!

Answer 2

The standard form of a linear equation is $ax+by=c$, where a, b, and c are numbers.

You are given $y-4=-2(x+7)$. We need to start by expanding and simplifying.

 $y-4=-2x-14\\y=-2x-14+4\\2x+y=-10$

Some teachers, including mine when I took Algebra 1, require that you find integers (whole numbers) for a, b, and c, and that a be positive. Here, we are fine.
