Hey teacher, how can you find the slope of a line if you aren't given an equation?
Glad you asked Tom, I'll show you when we get to class.
To find the slope, you are going to take two points that are on the line and that are also on the grid lines. Then you are going to find how many grid squares there are vertically (rise) and horizontally (run) between the two points. Then you calculate rise divided by run. If you calculated everything correctly, you should have gotten your slope.
Are there any other ways to find the slope?
Another way to find the slope is by first taking two points on the line. One of the points will give you your x1 and y1 values while the other point will give you your x2 and y2 values. Then you will calculate y2- y1 divided by x2-x1. That will give you the slope of the line.
