Write in 0 and 0 at the top:  this indicates that if there are zero pennies, the height of the tower is 0.  This is the point (0,0).  Another point is (4, 28):  a tower of 28 pennies is 4 cm tall.

Find the slope of the line connecting (0,0) and (4,28).
            4cm - 0 cm
    m = ----------------- = (1/7) (cm/penny)
            28 - 0

The equation we need, relating # of pennies to height of tower, is 

       t = (1/7) (cm/penny)x, where x is the # of pennies.

Thus, if x = 1, then t=1/7 cm

And, if x =15, then t = 15/7 cm

And so on.
