In this activity, we will be working out the gradient of a line on a coordinate grid.
There is just one important rule to remember.
Here it is!
The gradient of a line = y-step ÷ x-step
Example
Find the gradient of the red line.
Answer
First, we must find points with whole number coordinates on the red line in order to build a step.
The vertical part of the step (y-step) = 4
The horizontal part of the step (x-step) = 2
Gradient of line = y-step ÷ x-step = 4 ÷ 2 = 2
