Question

What is the slope of the line represented by the table below?
x y
10 22
25 49
35 67
60 112
90 166

A. 9/10
B. 3/2
C. 9/5
D. 27/10

Answer 1

9/5

If you choose two points you can find the equation change in y/change in x (y2-y1)/(x2-x1). Using the first two points this looks like:

(49-22)/(25-10)=27/15=9/5
