Find the slope of (0,1) (3,10) (6,19) (9,28) (12,37)

9/3 or 3
slope is rise over run. or x over y.
look at your Y points... 1, 10, 19, 28, 37. They go up 9 each time, right? 1 + 9 = 10 + 9 = 19...etc.

Now, look at your X points... 0, 3, 6, 9, 12. They go up 3 each time, right? 0 + 3 = 3 + 3 = 6...etc.

Since you go up 9 for the y axis and 3 for the x axis...

9/3
