Question

How do you graph `x+4y=-8`?

Answer 1

see explanation below

Explanation:

`x + 4y = -8`

check `x-`intercept when `y =0`
`x + 4(0) = -8`
`x = -8`
therefore, `x-` intercept at `(-8,0)`

check `y-`intercept, when `x =0`
`0 + 4y = -8`
`4y = -8`
`y = -8/4 = -2`
therefore, `y-` intercept at `(0, -2)`

mark these 2 points of intercept and make a straight line through these 2 points.
