Question

How do you find the x and y intercepts of `y=-1/2x+2`?

Answer 1

`"x-intercept "=4," 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"`

`x=0rArry=0+2=2larrcolor(red)"y-intercept"`

`y=0rArr-1/2x+2=0rArrx=4larrcolor(red)"x-intercept"` graph{-1/2x+2 [-10, 10, -5, 5]}
