Matching linear equations with their corresponding graphs is a fundamental skill in algebra and a crucial stepping stone for ...

The slope of a line, often denoted by the letter m, is defined as the ratio of the vertical change (rise) to the horizontal ...

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 ...

The gradient of a straight line describes the slope or steepness of the line. \(\text{Gradient =}~\frac{change~in~y}{change~in~x}\) To determine the gradient of a line: choose any two points on the ...

In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...
