Substitute 2 values for #x# and solve for #y# in order to find two points on the line and plot them. Then draw a straight line through them.

#y=-2/5x+2#

Find two points on the line.

Point A:

#x=0#

#y=-2/5*0+2#

#y=0+2#

#y=2#

Point A#=##(0,2)#

Point B:

#x=5#

#y=-2/5*5+2#

#y=-10/5+2#

#y=-2+2#

#y=0#

Point B#=##(5,0)#

Plot point A and B, then draw a straight line through them.
