#"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 = o, in the equation for x-intercept"#

#x=0to0+y=4rArry=4larrcolor(red)" y-intercept"#

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

#"plot "(0,4)" and "(4,0)" and draw a straight line"#
#"through them"#
