Description: Give your students a beginner's strategy to calculate the equation of a line given slope and 1 point by extrapolating from the graph to determine the y-intercept. Students will put together the given rate of change and y-intercept to make the equation of a line in slope-intercept form (y=mx+b). This makes a great introductory activity before the abstract concept of algebraic substitution is introduced. RESOURCE INCLUDES: 10 questions graph with given point fill-in-the-blanks
