The equation used for finding slope (m) is:
(slope equals the change in y over the change in x)where D 1.
First, find the coordinates of two points on the line. The coordinates of one point will
be labeled ( 2. Next, find the change in D 3. By definition, slope is the "rise over
the run", or the m = D Since this data is linear, you will get the
same slope no matter which points you choose. The slope of the line is constant and equal
to .75. This means that every increase of .75 units on the *The change in Copyright © 1997 Central Virginia Governor's School for Science and Technology Lynchburg, VA |
