#"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=0toy=0-2rArry=-2larrcolor(red)"y-intercept"#

#y=0to3/4x-2=0rArr3/4x=2rArrx=8/3#

#"choosing another value of x since "8/3" is awkward"#

#x=4toy=3-2=1#

#"plot the points "(0,-2)" and "(4,1)#

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