Test Corrections c If you weren’t done yet, I’ll give your test back to you tomorrow. Otherwise, expect to see TCs in IC by the end of the week. c Turn in your worksheet/ graph picture. (Not due until tomorrow) 9.1 and 9.2 Inverse Variation and Graphing Objectives c Identify Inverse Variations c Graphing inverse variations Reminder c What is direct variation? What does the graph look like? c Form of c Example: y = kx X 1 2 3 Y y = 4 x Inverse Variation c What might inverse variation mean? What does the graph look like? c Form of: OR: c Ex. y = k x yx = k X 1 2 3 Y y = 3 x Inverse Variation Example c Graph the relationship between a bike’s speed and the time it takes to travel 24 miles. Rate (mi/h) Time (h) 3 8 6 4 12 2 24 1
