#### 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-y=-8rArry=8larrcolor(red)"y-intercept"#

#y=0rArr2x=-8rArrx=-4larrcolor(red)"x-intercept"#

#"Plot the points "(0,8)" and "(-4,0)#

#"Draw a straight line through them for graph"#

graph{(y-2x-8)((x-0)^2+(y-8)^2-0.04)((x+4)^2+(y-0)^2-0.04)=0 [-20, 20, -10, 10]}
