Enter the expression 2x into the red pan, and enter the expression x + 4 into the blue pan. Enter the value x = -5 into the box near the top. What happens? Change the value of x to 0 and then to 5. How does this change the relationship between the pans? Move the slider to adjust the value of x. For what value of x do the red and blue pans have equal values? What happens in the graph when the values of the pans are equal? Explain the relationship between the values of the pans and the graph.
