Answer:

#"see explanation"#

Explanation:

#"one way is to find the intercepts and draw a "#
#"straight line through them"#

#color(blue)"to find the intercepts"#

#• " let x = 0, in the equation for y-intercept"#

#• " let y = 0, in the equation for x-intercept"#

#x=0to0-5y=80rArry=-16larrcolor(red)" y-intercept"#

#y=0to8x-0=80rArrx=10larrcolor(red)" x-intercept"#

#"plot these 2 points and draw a straight line through them"#
