"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"
