Question

What is the slope for the following data?

X -1 0 1 2

Y 0 1 2 3

y2 - y1
----------
x2 - x1

rise / run

Answer 1

well, geez. You have the formula. Pick any two (x,y) pairs and plug them in:

(3-0)/(2+1) = 1

You can see just by looking at the table that when x increases by 1, so does y.

Answer 2

You have found the slope.
