In this lesson, you will learn how to graph an equation in Algebra. We first learn that an equation consists of independent and dependent variables, then use this to create a table of values. We supply an input value to the function, which we call the independent variable, then calculate the output value, which we call the dependent variable. We then use these values construct (x,y) pairs of points and plot them on the xy plane. When graphing equations, we may obtain many different graphs. Most commonly we get a line, or linear, graph. We may also get a quadratic (parabola), or cubic graph or many other shapes.
