Question

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

Answer 1

(0,-2)

`(1/2,0)`

Explanation:

`4x-y=2`

Put `x=0, y=-2`

Put `y=0, x =1/2`

Answer 2

`"x-intercept "=1/2," y-intercept "=-2`

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"`
