1. 5.4 The Slope Formula

2. Language Goal  Students will be able to verbally explian how to find slope. Math Goal  Students will be able to find slope using the slope formula. Essential Questions  What is the important information we can get from finding the slope?

7.  Find the slope of a line passing through(-3, 0) and (-1, 6)

8. Find the slope of the line passing through (-2, 1) and (1, -3)

9. Find the slope of the line passing through (5, 0) and (0, 2)

10. Find the slope of the line passing through (-1, -3) and (5, -3)

11. Find the slope of the line passing through (0, -1) and (0, 4)

12.  On your notecard write an ordered pair (x, y).  Your x and y coordinate may contain any number between -10 and 10.  Fractions are allowed too.  Once it is written on your notecard wait until further instructions.

13.  You will partner with someone in the class  Use your two points to determine the slope of the line.  Once you have found your slope determine whether your slope is positive, negative, no slope or undefined.  We will rotate as a class.

14. Find the vale of y so that the line passing through the points (-3, y) and (1, 5) has a slope of -2.

15. Find the vale of y so that the line passing through the points (3, y) and (5, 8) has a slope of 2.

16.  First, use the table to write two ordered pairs.  Then, use those two points to calculate slope using the slope formula.

17. x0256 y151113 Find two ordered pairs from the table. Use the ordered pairs to calculate slope.

18. x-2024 y30-3-6 Find two ordered pairs from the table. Use the ordered pairs to calculate slope.

19. x-2024 y30-3-6 Find two ordered pairs from the table. Use the ordered pairs to calculate slope.

20.  Step 1: Find the x – intercept  Step 2: Find the y – intercept  Step 3: Use the slope formula

23.  Pass out Whiteboards or students can do in notebook.  Go over as a class.
