Find the Proportionality Constant of a Linear Equation

Problem Statement:
In this activity you will determine the proportionality constant of a linear equation. The board blocks will display two points on the grid. Change the values of 0 in the blocks to graph the line through these points. Then run the program to see if your graph is correct and answer the question. Use the graph to determine the proportionality constant for the proportional relationship between x and y.
