This pre-algebra math tutorial from NutshellMath offers targeted homework help on problems involving graphing linear functions. The instruction focuses on problems 17-29, 39, and 43-45 on pages 529 and 530 of the Prentice Hall Mathematics, Course 2 text. Linear equations are a subset of equations that graph to be a straight line. With a linear equation, every point on the line represents a single solution from the solution set, and no other solutions besides those on the line exist for the equation.
The problems targeted by this tutorial involve determining whether or not an equation is a linear equation. One method of determining the linearity of an equation is to graph the equation and determine if the graph is a line. To do so, pick several values for x and set up a table including the x-values, the equation, and the corresponding y-value. Solve for the corresponding y-values and enter the values into the table. Plot all the points on a coordinate plane. At least three points must be graphed to determine the linearity of a graph. If all of the points lie on a straight line, then the graph can be considered linear.
Linear equations are one of the most basic forms of relationships between two variables. Determining whether an equation is linear by graphing is a first step in recognizing linear equations, and is a technique that can be used to solve homework problems such as those covered by this tutorial. Problems such as these will aid in understanding and recognizing what types of relationships between two variables are linear relationships.
