Question

How do you turn 8x-4y=20 into slope intercept form? Please show me the steps

Answer 1

Answer:

$y = 2x - 5$

Step-by-step explanation:

$y = mx + b$

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

$- 4y = 20 - 8x$

Move 8x to subtract.

$y = \frac{20 - 8x}{ - 4}$

Pull the negative out of 4.

$y = - \frac{20 + 8x}{4}$

Simplify

$y = - \frac{20}{4} + \frac{8x}{4} \\ y = - 5 + 2x$

Swap x-term and constant.

$y = 2x - 5$
