Answer:

#"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"#
