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 ...

A horizontal line means the object is moving at a constant speed. The gradient of the line = the rate of change of speed. The steeper the line, the greater the increase in speed. The area under the ...

Plotted points on a graph are referred to as coordinates. Coordinates are pair of numbers written in the form \(({x},~{y})\) where \({x}\) is the amount moved horizontally, and \({y}\) the amount ...
