Question

How do you graph the equation `y-8=-x`?

Answer 1

`"see explanation"`

Explanation:

`"one way is 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-8=0rArry=8larrcolor(red)"y-intercept"`

`y=0rArr0-8=-xrArrx=8larrcolor(red)"x-intercept"`

`"plot the points "(0,8)" and "(8,0)`

`"draw a straight line through them for graph"`
