Suppose that Y=MX+b, where Y=consumption, b=consumption at zero income M=slope and Xincome.

Are Yand X positively related or are they negatively related? 

If graphed would the curve for this equation slope upward or šlope downward? 

Are the variables Y and Xinversely related or directly related? 

What is the value of Y if b = 11 M = 50 and X = 200?

What is the value of Xif Y = 100 b = 10 , and M = 25.
