Answer to Question 1

TRUE

Answer to Question 2

The graph of the line with the positive slope should be upward sloping, while the graph of a line with a negative slope should be downward sloping. When the line is upward sloping, this implies that as the variable on the x-axis increases the variable on the y-axis also increases. These two variables move in the same direction. When the line is downward sloping, this implies that as the variable on the x-axis increases the variable on the y-axis decreases. The two variables move in opposite directions.
