Slope of a line

Determine the slope of a line

1. Determine the slope of a line using the graph.
The slope (also called: gradient) of a line is the ratio of the change in y compared to the change in x.

Look at the picture and determine the slope:

2. Determine the slope of a line from two points

You can determine the slope of a line finding two points P(x ₁,y₁) and Q(x₂,y₂) on the line and using the following equation:

Look at the picture and determine the slope:

The slope (gradient) is m =
