Suppose that someone said that the equation connecting points (-1, 1) and (2, 3) is y=2/3x+ 5/3. This person wants to know whether the line represented by this equation will contain point (6, 9). Identify two ways by which this person can decide whether the graph of the equation contains the point.

• math -

1. see if the point (6,9) satisfies the equation

2. use (6,9) with one of the other points and see if you get the same equation
