An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight ...

Look for Key Features: Identify critical points and characteristics such as intercepts, vertices, asymptotes, and symmetry. Test Points: Choose a few points on the graph and plug their coordinates ...
