3. Recognizing How Changes in Linear Equations and Functions Affect Their Graphs

Now that we are comfortable with slope intercept form, or y=mx+b, we can look at the what happens when you change the values of m and b. The new graph is related to the original graph but there is a slight … Continue reading

2. Graphing Linear Equations and Functions Using a Variety of Methods

You can graph a linear equation or function by 1. making a table, 2. using intercepts, or 3. using the slope and y-intercept. We saw earlier the various ways to represent functions using words, algebraic expressions, tables, and graphs. We … Continue reading

1. Graphing in the Coordinate Plane

Becoming comfortable with the coordinate plane (also known as the Cartesian plane) is essential to success in graphing. Once you understand this mathematical “map” and can work with it comfortably, you will be able to transfer that understanding to any … Continue reading
