When two variables move in opposite directions, the curve relating them is upward sloping, and we say the variables are positively related.

Opposite Directions

A term indicating movements or trends that are diametrically contrary to each other in a physical or metaphorical sense.

Upward Sloping

A term often used to describe a line on a graph that shows an increase in a variable as another variable increases, indicative of a direct relationship.
