How do you graph ## y = -2/5x + 2##?

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.
