How do you graph a line in slope-intercept form?

• Identify the y-intercept and use the slope to find additional points on the line.

• Use the x-intercept and the slope to find additional points on the line.

• Plot random points on the graph and connect them to form a line.

• Use the slope and the x-intercept to find the y-intercept.
