1. January 12 Homework: Calculating Slope Worksheet Warm-up: 1. Linda has $26. She earns $6 for 1 hour (h) of babysitting. She wants to buy a ski pass for $80. Write an inequality that shows the number of hours (h) Linda could babysit to be able to buy the ski pass. 2. Write a number line that shows the solution to the inequality –3x – 5 < –2? (Hint… What steps do you use to solve for x?)

3. How do we measure the “steepness” of a graph or line?

4. “Steepness” of a graph is called… SLOPE! How do I find the slope of a line?

5. How to find the slope of a line when given a graph Step one: Identify two points that you know for sure are on the line. Step two: Draw in a “slope triangle.” Step three: Identify the base and height of the triangle (from left to right). 2 4 Step four: Write the dimensions of the triangle in a fraction with the “rise” as the numerator and the “run” as the denominator. = ½
