A 3cm by 5cm picture is enlarged by a factor of 2.5. (You do not need to include units in your answers for this problem. Do not round on any answers.)

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
