Question

How do you find the x and y intercept given `y=4x+4`?

Answer 1

`y-`intercept `=4`

`x-`intercept `=-1`

Explanation:

`y=4x+4`

For finding `y`-intercept , put x = 0.

`y=4(0)+4`

`y=4`

For finding `x`-intercept , put y = 0.

`0=4x+4`

`-4=4x`

`-1=x`

Answer 2

`-1" and "4`

Explanation:

`"to find the intercepts, that is where the graph crosses"`
`"the x and y axes"`

`• " let x = 0, in the equation for y-intercept"`

`• " let y = 0, in the equation for x-intercept"`
