In order to work with gradients and straight lines successfully, a good understanding of coordinates and linear graphs is needed. The gradient of a line is calculated by dividing the difference in the ...

Any straight line graph has a constant gradient, which is calculated by the change in 𝑦 divided by the change in 𝑥, along any section of the graph. The gradient is measuring the steepness of the ...

Let's look at the idea of what an x and y intercept are. Basically, an x intercept is where it intercepts the x axis, and the y intercept is where it intercepts the y axis. Say if I drew any line ...
