"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=0rArr-2y=8rArry=-4larrcolor(red)"y-intercept"

y=0rArr-x+8=0rArrx=8larrcolor(red)"x-intercept"

"plot the points "(0,-4)" and "(8,0)

"draw a straight line through them for graph"
graph{(y-1/2x+4)((x-0)^2+(y+4)^2-0.04)((x-8)^2+(y-0)^2-0.04)=0 [-10, 10, -5, 5]}
