Question

What is the slope-intercept form of `8x - 4y = 16`?

Answer 1

2

Explanation:

Make sure that the standard form turns into slope-intercept form (which is `y = mx + b`).

Therefore, bring 8x to the other side of the equal sign by subtracting it from both sides.
`8x - 8x - 4y = 16 - 8x`
`-4y = 16 - 8x`

Isolate y by dividing all of the terms by -4.
`(-4y = 16 - 8x)/(-4)`

`y = -6 + 2x`

Remember that in `y = mx + b`, the m represents the slope.

In this case, 2 is the coefficient with x.

Therefore, the slope is 2.
