Answer to Question 1

A direct relationship will slope upward; it will have a positive slope. An inverse relationship will slope downward; it will have a negative slope. A change in some relevant variable other than those listed on the vertical or horizontal axis must change in order to shift a line or curve expressing a relationship between two variables.

Answer to Question 2

A direct relationship between two variables means an increase in the value of the independent variable will cause an increase in the value of the dependent variable; and vice versa. An example would be the relationship between the selling price of a good and the amount of the good put up for sale by producers. An inverse relationship between two variables means an increase in the value of the independent variable will cause a decrease in the value of the dependent variable; and vice versa. An example would be the relationship between the price of a good and the amount purchased.
