Question

How do you find the intercepts for `2x-4y=12`?

Answer 1

You find the `y`-intercept by setting `x=0` and vice versa.
But you may first divide everything by `2`

Explanation:

`->x-2y=6`

`y`-intercept:
`0-4y=12->y=12/-4=-3->(0,-3)`

`x`-intercept:
`x-2*0=6->x=6->(6,0)`
graph{0.5*x-3 [-6.04, 13.96, -6.88, 3.12]}
