Ms. Yardley wrote four sets of ordered pairs on the whiteboard for her math students. For which set is y a function of r?
0 (-3, -2), (3, - 2), (-2, 1), (2, 1), (0, 0)

(4, - 2), (4, 2), (2, – 4), (2, 4), (4, 4)

(-1, 2), (4, 3), (-1, 5), (-6, - 2), (-2, 1)

(0, 2), (4, 5), (-3, – 3), (0, - 1), (6, - 2)

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)
