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 ...

The slope of a line can be 'seen' to be sloping uphill or to be sloping downhill. The examples so far have been sloping uphill as you look at the diagrams from left to right. When a line is sloping ...

In math and statistics, you may occasionally need to calculate the slope of a line generated by coordinates in the (x,y) format. The slope is a value that indicates the rate at which the y value of a ...
