Question

How do you find the x and y intercepts for `y=2x+2`?

Answer 1

`x` intercept is `7/4` and `y` intercept is `7/3`.

Explanation:

For `y=0`,
`color(white)(xx)2x+2=0`
`=>2x+2color(red)(-2)=0color(red)(-2)`
`=>color(red)(1/2xx)2x=color(red)(1/2xx)(-2)`
`=>x=-1`

Therefore `x` intercept is `-1`.

For `x=0`,
`color(white)(xx)y=2xx0+2`

Therefore `y` intercept is `-2`.
