The dotted red line has the equation y = mx + c. Change the values of M & C and see what happens to the red line.
What effect does changing the value of C have if you keep M constant? What effect does changing the value of M have if you keep C constant? What happens when C=0? What happens when M=0? Change the value of M and C so that the red line matches up with the black line. Is it always possible to make the red line match up with the black line?
