After graphing a data table, it’s common to “see” a pattern in the points. If we believe our data has a pattern, we try to use an algebraic function to approximate the pattern. The simplest function is one that has two variables and is based on a product and a sum. This function is often called a linear function and it’s a good choice if your graphed data looks like it might be approximated by a straight line. After completing these videos you'll be able to find and apply two important features of a linear function, the slope and the y-intercept. This information is covered on pages 75-81 in our textbook.
