Formula to find gradient in co-ordinate geometry?

We can find m directly by looking at the change in vertical distance divided by the change in horizontal distance also know as the rise over the run. This give us m, the gradient. Anotther way is if we have the equation of the line, then the slope or gradient can be determined immediately from that. The equation of a line in slope-intercept from is y=mx+b and m represents the slope.
