Comparing linear functions: table vs. graph (1) (Full video)

Khan Academy

Supporting grades: 8

Description: Sal is given a table of values of a linear function and four linear graphs, and is asked to determine which graph has the same rate of change as the function represented in the table. Created by Sal Khan. f is a linear function whose table of values is shown below. Which graphs show functions which are increasing at the same rate as f? So we could just look for which of these lines are increasing at a rate of 7/4, 7 in the vertical direction every time we move 4 in the horizontal direction.
