5. Convert the following standard equation to slope-intercept form (y =
mx + b) and identify the slope: 8x + 2y = 20 *

Answer 1

y = -4x +10

Slope = -4

Explanation:

`8x + 2y = 20`

Slope intercept form =

`y = mx + b`

`2y = - 8x + 20`

Divide both sides of the equation by 2

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

Simplify

`y = - 4x + 10`

In y= mx+b , m is the slope and the coefficient of x

`m = - 4`
