Problem:
An equation, y = 3x + 5, is graphed. A second equation is then given which
changes the coefficient 3 to the number 2, thus giving the equation y = 2x + 5.
1. Describe the effect of the change on the x and y-intercepts.
2. Describe the effect of the change on the slope of the line.
3. Describe the effect of the change on what’s happening with the graph.
