Graphing a Line Using Slope-Intercept Form

This video tutorial explains how to graph a line using the slope-intercept form, y = mx + b. It covers identifying the y-intercept and slope from the equation y = -2/3x - 5. The tutorial demonstrates how to plot the y-intercept and use the slope to find additional points on the line. The video concludes with a practical example of graphing the line by moving down two units and right three units from the y-intercept.

What is the general form of the slope-intercept equation?

• y = mx - b

• y = bx + m

• y = mx + b

• y = ax + b
