Analyzing Multiple Representations of Linear Functions, Worksheet 1 A linear function is shown as an equation, a table, and a graph. Analyze the different representations to answer the questions below. 1. What is the slope of the linear function? Which representation shows the slope most easily? Why? 2. What is the pattern to the increase in y-­‐values? Which representation clearly shows this pattern? Why? 3. What is the y-­‐intercept of the function? Which representations clearly show this? 4. To evaluate f(25.5) which representation is best to use? What is f(25.5)? 5. Suppose you have a data set that you think is a linear function. Describe how you would determine whether it is or isn’t. © Media4Math. 2015. All rights reserved. Answer Key 1. 2
