Hitting the Slopes

OBJECTIVE: To understand the concept of the slope of a line

When you look at the graphs of linear equations, you'll observe that the lines slant in different directions. The slant may be upward from left to right, downward from left to right, perfectly horizontal or perfectly vertical. This slant is called the slope of the line. THE FOUR TYPES OF SLOPES Move one or both dots in the applet below to discover the four types of slopes.

QUESTION: In your own words, describe each of the four types of slopes.

Now that you've discovered the four types of slopes, can you match the type of slope with the graph?

For each new line shown, choose the correct type of slope from the four choices at the right. Repeat until you have mastered the concept.

QUESTION: Which type of slope appeared most often? (Answers may vary.)

Now let's do more than just clicking the mouse!

This final activity asks you to match the given type of slope with an appropriate graph. Are you up to the challenge? Repeat until you have mastered the concept.

QUESTION: Which type of slope did you find hardest to produce? (Answers may vary.)
