1. Do symmetry tests examples
Show how to show work

2. 1.3 Review of linear equations

3. If Slope is the steepness of a line, how can we calculate this “steepness”
Slope is equivalent to rise over run
Slope = =
rise is vertical change (y’s)
run is horizontal change (x’s)

4. The Huashan Trail in China

5. Other considerations

6. How to remember – Mr. Slope Man!

7. Why m for slope?
Some say from the french word “montant” meaning rising
However, in France they use s from the English word slope.
So yes, math books around the world are working hard trying to confuse you.

8. Slope Intercept
Point Slope

9. Ex
Find the equation of a line that has a slope of 4 and passes through the point (-2, -3)

10. Parallel lines have the ……….. Slope
Same
Parallel lines have the ……….. Slope
Slopes of perpendicular lines are ………
…………. of each other
Negative
Reciprocals
