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.
