2-9 Write the domain and range for each of the following graphs. Drag the symbols below to answer the domain and range questions.

The x value for point B that is located ¼ the distance from point A to point C is -0.75. Point A which is (0,4) and point C (-3,5) are the given values in the problem. It is assumed that point A is 75% while point C is 25%.
To determine the x-value, 
¼(-3) + ¾(0) = -¾ = -0.75
