This chapter outlines linear functions and graphs in several variables. It presents plotting in 3-D and the case of linear functions in detail. The main idea of differential calculus is that smooth functions microscopically look like linear functions so one needs to understand the linear case ...
All linear functions cross the y-axis and therefore have y-intercepts. (Note: A vertical line parallel to the y-axis does not have a y-intercept, but it is not a function.)How To: Given the equation for a linear function, graph the function using the y-intercept and slope...
Graph linear functions. Write the equation for a linear function from the graph of a line. Given the equations of two lines, determine whether their graphs are parallel or perpendicular. Write the equation of a line parallel or perpendicular to a given line. Solve a system of linear equatio...
Graphs of Linear Functions A linear function is an equation that when graphed, creates a perfectly straight line. The equation for a linear function is of the form: f(x) = mx + b. The variables m and b will be replaced with numbers. The variable m represents the slope of the line ...
Chapter 1 Linear Equations and Graphs Section 2 Graphs and Lines 2 The Cartesian Coordinate System The Cartesian coordinate system was named after René Descartes. It consists of two real number lines, the horizontal axis (x-axis) and the vertical axis (y-axis) which meet in a right an...

These all represent the same graphs. Examples of linear functions: f(x) = x, f(x) = 2x – 2, f(x) = x + 1. Domain and Range of a Linear Function The domain and range of a linear function is usually the set of real numbers. There is an exception: if the function is ...
