This resource provides an overview of graphing for various types of functions, instruction on graphing straight lines and also, includes advice on common mistakes made by students.

This math tutorial shows the relationship of a slope to a straight line and how to write equations in point-slope or slope-intercept form.

In this part of a physics lesson, examine how the actual slope value of any straight line on a velocity-time graph is the acceleration of the object.

In the following interactive module students will describe a straight-line graph in terms of its slope and y-intercept. They will determine average velocity or instantaneous velocity from a graph of position vs. time.
