In this video, we provide essential "math help" by explaining how to "graph" piecewise functions. This "math tutorial" breaks ...

The graphs above, \(y = 2x + 1\) and \(y = 2x - 2\) have the same gradient of 2. The lines are parallel. State the equation of a line that is parallel to \(y = 3x + 7\). To be parallel, two lines must ...

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 ...
