Question

How do you turn 8x-4y=20 into slope intercept form?

Please show me the steps

Answer 1

`y = 2x - 5`

Explanation:

`y = mx + b`

We need to leave y-term as the subject of equation.

`- 4y = 20 - 8x`

Move 8x to subtract.

`y = (20 - 8x)/( - 4)`

Pull the negative out of 4.

`y = - (20 + 8x)/(4)`

Simplify

`y = - (20)/(4) + (8x)/(4) \\ y = - 5 + 2x`

Swap x-term and constant.

`y = 2x - 5`
