How can you use the slope and y intercept to graph an equation?

To graph a linear equation in slope-intercept form (y = mx + b), identify the slope (m) and the y-intercept (b). Start by plotting the y-intercept on the y-axis at the point (0, b). Then, use the slope to determine the rise over run; from the y-intercept, move up or down (rise) and left or right (run) to plot another point. Finally, draw a straight line through these points to complete the graph.
