Match the equation to its graph

Six equations, six members of the family. Use the elimination looks: direction first (the sign of m), then where it crosses the y-axis (b), then steep or gentle. Each grid runs from −5 to 5, and the dot marks where the line crosses the y-axis.

Where to go next

Next: Each number does its job: change only m, or only bm and b are the two numbers that pick one line out of the family, so they are exactly what let you eliminate. All the partsThe Family of Lines: One Form, Many Members
