When you’re given coordinates
When you are given coordinates for two points on a straight line finding the gradient is logic based on what you already know.
Example
Given 10, 8 and 6, 6 find the gradient of the line.
First plot on a graph to help visualise.
Gradient (m)=y(change in)x(change in)
Then draw the line between the points.
Now work out the horizontal (x) and vertical (y)
Gradient (m)=+2+4=12
Gradient of this line (m)=12=0.5
