All it takes is two points on a line to determine slope. The rise and run between any two points are roughly equal so the slope is about 1. 5 Steps for Finding Slope from a Graph Worksheet Example Find the change in the y-values.
Starting with the point on the left sketch a right triangle going from the first point to the second point.
The slope equals the rise divided by the run. Then I know its second order. One point is easy to spot because its also on the graph of f itself. Finding the Slope of a Line from a Graph You can determine the slope of a line from its graph by looking at the rise and run.
