Question

How do you find the slope and y intercept for `x+2y= -8`?

Answer 1

The slope is `-1/2` and the y-intercept is `-4`.

Problem: Find the slope and y-intercept for `x+2y=-8`.

Convert the equation into the slope-intercept form.

The slope-intercept equation is `y=mx+b`, where `m` is the slope, and `b` is the y-intercept.

`x+2y=-8`

Subtract `x` from both sides of the equation.

`2y=-x-8`

Divide both sides of the equation by `2`.

`y=-1/2x-4`

`m=-1/2`

`b=-4`
