see explanation.

Explanation:

To find the intercepts.

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

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

#y=0to2x+0=8rArrx=4larrcolor(red)" x-intercept"#

#x=0to0+y=8rArry=8larrcolor(red)"y-intercept"#

Plot the points (4 ,0) and (0 ,8) draw a straight line through them and you have the graph of 2x + y = 8
