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 ...

When you graph a series of (x,y) coordinates in Microsoft Excel 2010, you can use the program's built-in functions to display the equation for the line created by those data points. This allows you to ...

A straight line drawn on a grid can be described by a rule connecting the x and y coordinates of every point on the line. This is known as the equation of the line. The equation of any straight line ...

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 ...

The straight line through two points will have an equation in the form \(y = mx + c\). We can find the value of \(m\), the gradient of the line, by forming a right-angled triangle using the ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...
