y is a(n) _____________
Can any of the expressions above be simplified? YES NO
Evaluate the following expressions given x = 10, y = 5, and z = 3. Show all your work!
x + y + z
6. (yz) ÷ x
7. 10x – 10y

8. (z + x ) – y
9. 10yx – z

Using the graph at the left, label the x-axis and y-axis. Then graph and label the
following points. Write which quadrant each point is in or axis it is on.
A (3,-1)
B (-1,3)
C (5,-2)
D (-1,-3)
E (0,4)
F (-3, 0)
