Graph a Line Representing a Proportional Relationship Formative Assessment - Just in Time Quick Check, Teacher Notes, and Supporting Resources

In the Racing Away lab, students will understand the physical meaning of slope as a rate of change and the y-intercept in distance vs. time plots. Students will also come to understand the meaning of each part of writing a linear equation in two variables in slope-intercept form.

In this lab, students will determine the slope of a line when given two points on the line; write the equation of a line when given the graph of the line, two points on the line, or the slope and a point on the line; and graph linear equations in two variables. Throughout the lab, students make connections between and among multiple representations of functions using verbal descriptions, tables, equations, and graphs.
