Gradient is the measure of the slope of the graph.

It is measured by finding change in y divided by change in x. Formula of gradient is written on right.

Finding gradient of straight line

GRADIENT OR SLOPE​

In this graph, select any two points and using the formula in the previous slide, we can find the gradient.

Example 1

EXAMPLE 1:

Using these two points, (0,3) and (1, 5), we can label the points and substitute in the formula.

Example 1 (continued)

EXAMPLE 1:(contd)

​

Now, we substitute the two points we chose from the graph which lie on the line into the formula of gradient, and find the solution.
