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=02y=8y=4y-intercept

y=0x+8=0x=8x-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]}
