Example 1

Mr. Taggart is calculating his students’ test scores on a 25-question test with the equation [math]y = 4x + 3[/math], where [i]x[/i] is the number of correct questions and [i]y[/i] is the score. Make a table of values and create a graph of this relationship.

[list=1] [*]Determine values that make the equation true. [*]Organize these values in a table. [*]Plot the ordered pairs from the table on a coordinate plane. [*]Draw a line through the points.
