Exploring Slope And Intercept Worksheet Page 3

16. Sketch the following equations on your graphing calculator.

y = 2x + 3

y = 2x + 7

y = 2x - 1

Describe the graphs.

17. What similarities do the graphs have?

18. What differences do the graphs have?

19. What conclusion can you determine about

graphs of equations of the form

y = some negative number times x +/- some number?

20. How would you describe the graph of y = 5x + 3 compared to y = 5x - 2?

21. Is there a shortcut to graphing equations in the form

y = some number times x +/- some number?

22. This form is called slope-intercept form. It is written y = mx + b. You have just

discovered another way of graphing!!

M stands for

and B stands for

What is the shortcut for graphing these equations?

Step 1:

Step 2:

23. List the three different ways of graphing.
