In this lesson you will learn how to recognize a linear function by examining the four representations of a function. read more
Graph Linear Functions Using Slope and y-Intercept. Another way to graph a linear function is by using its slope m, and y-intercept.. Let’s consider the following function. read more
Linear functions have a constant rate of change and describe a straight line on a graph. Linear functions can be defined by the equation y = mx + b. Proportional functions are linear functions that include the origin and can be defined by the equation y = kx. read more
