Answer:
increasing-positive slope
decreasing-negative slope
constant-zero slope
Step-by-step explanation:
Positive slope would be the graph increasing because the line would be going up and to the right.
Negative slope would be the graph decreasing because it would be going down, and to the right.
Zero slope would be constant since it does not change.
