**The Slope-Intercept Equation**

The equation y = mx + b is called the slope-intercept form of a line.

The equation represents a line where m = slope and b = y-intercept (0, b)

The following diagrams show how to graph a line using the slope-intercept method. Scroll down the page for more examples and solutions.
