Slope-Intercept Form of a Line
1. Fill in the table for each function. Plot the points from the tables on the coordinate planes. Use a
ruler or straightedge to draw a line through the points.

2. Calculate the slope (m) of each function in problem 1. You may either find the rise and run
directly from the graph or use the slope formula to get your answer. Leave your answer as a
fraction in simplest form. Hint: Pick 2 easy points from each line to work with.
Line (a) m=
Line (b) m=
3. Do the slopes you just calculated appear anywhere in the functions from problem 1? If so,
where do they appear?
4. Find the y-intercept of each function. Remember: the y-intercept is the point where the line
crosses the y-axis.
Line (a) y-intercept:
Line (b) y-intercept:
5. Do the y-intercepts you just found appear anywhere in the functions from problem 1? If so,
where do they appear?
