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=0⇒−2y=8⇒y=−4←y-intercept
y=0⇒−x+8=0⇒x=8←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]}
