Question

How do you find the slope and intercept of `4x+8y = -64`?

Answer 1

If `Ax+By+C=0`
Then `Slope=-A/B`, x-intercept`=-C/A` and y-intercept`=-C/B`.

`4x+8y=-64`
`implies 4x+8y+64=0`
`implies x+2y+16=0`

Here `A=1, B=2 and C=16`

`implies Slope=-1/2`, x-intercept`=-16/1=-16` and y-intercept`=-16/2=-8`

`implies Slope=-1/2`, x-intercept`=-16` and y-intercept`=-8`
