1 5-1 SLOPES MISS BATTAGLIA – ALGEBRA 1 CP OBJECTIVE: CALCULATE THE SLOPE OF A LINE AND DRAW A LINE THROUGH A POINT WITH A GIVEN SLOPE.

2 WARM UP What do you think the word slope means? Make a list of things that vary in slope.

3 COUNTING UNITS TO FIND SLOPE

4 AIRPLANES The graph models the altitude of an airplane from the time the wheels are lowered (time=0s) to when the plane lands. Find the slope of the line.

5 USING COORDINATES TO FIND SLOPE

6 EXAMPLE Find the slope of a line through the points A(0,-1) and B(3,4)

7 FIND THE SLOPE OF THE LINE USING THE POINTS SHOWN.

8 EXAMPLE

9

10 SLOPE OF LINES

11 HOMEWORK Pg 217-218 # 1-15 odd, 25
