Linear functionsGraphical representationThis study focuses on connections between linear functions and their graphs that were made by tertiary remedial algebra students. In particular, we describe students' work on a Task designed to examine the connection between points on a graph and the equation of...
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 ...
Graph Linear Functions Using Slope and y-InterceptAnother way to graph a linear function is by using its slope m, and y-intercept.Let’s consider the following function.f(x)=12x+1f(x)=12x+1The slope is 1212. Because the slope is positive, we know the graph will slant up...
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...
Linear functions are any functions that produce a straight line graph. So by definition, nonlinear functions produce graphs that aren’t a straight line. Linear function (red) and two nonlinear functions: exponential (blue) and polynomial (green). Graph created with Desmos.com. Nonlinear Function...

Quadratic and linear functions can both be graphed and will appear quite different visually. Learn the basics of bridges on graphs, parent graphs, and how linear and quadratic functions are each graphed. Bridges Have you ever seen a bridge before? They are perfect examples of real-world graphs...
Linear equation, statement that a first-degree polynomial—that is, the sum of a set of terms, each of which is the product of a constant and the first power of a variable—is equal to a constant. Specifically, a linear equation in n variables is of the
