Following the Line
functions · slope and linear equations from graphs
To write a linear equation from a graph and to find the slope from two points [8.F.B.4].
Following the Line is a Grade 8 functions activity that moves from points to a complete linear equation. Teams use card values to create two ordered pairs, plot and connect the points, calculate slope, determine the intercept, write the equation, and then use it to find additional points. The staged structure shows how graph, rate of change, intercept, and equation are connected parts of the same linear relationship.
Use it for small-group or whole-class review when students are ready to connect multiple representations of a line. Have teams explain how each stage provides information for the next.
