The question below are based on the following four sets of data-pairs: (1) A and B, (2) C and D, (3) E and F, and (4) G and H. In each set, the independent variable is in the left column and the dependent variable is in the right column.  The slope of the linear graph that pictures data set 2 above is:
A) .10 
B) 20 
C) 5 
D) 10

To find the slope of a linear graph, we divide the change in the y-variable by the change in the x-variable. In this case, the change in the y-variable (from C to D) is 100 units (400-300) and the change in the x-variable is 10 units (2-(-8)). Therefore, the slope is 100/10 = 10.
