Finding the Slope of a Line from a Table
lakkis [162]

Answer:

m = rise / run = 1/7

Step-by-step explanation:

Recall that the slope of a line is m = rise / run.

Here we look at x first (to calculate the run):  x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.  

Now look at how y behaves (find the rise):  y begins at 0 and ends at 1. Thus, the rise is 1.

Therefore the slope of the line connecting the two poings given is

m = rise / run = 1/7
