Final answer:
The term that describes the "tilt" or steepness of a line graph is the slope.
Step-by-step explanation:
The term that describes the "tilt" or steepness of a line graph is the slope.
Slope is defined as the change in the vertical axis divided by the change in the horizontal axis. It measures how much the line rises or falls as you move horizontally along the graph. A positive slope means that as the line moves from left to right, it rises, indicating a positive relationship between the variables.
