Bell Ringer #61 Objective Be able to solve proportions using cross-products #62 Objective Be able to use rise over run to find slope of a line

Lesson 44 • Solving Proportions Using Cross Products • Slope of a Line : 

Lesson 44 • Solving Proportions Using Cross Products • Slope of a Line

Slide 3: 

We replace the m in the original proportion with 6 then we simplify both ratios. If the ratios reduce to the same ratio, then they are equal. Both and reduce to , so our solution is correct.

Slide 4:
