Sure! Here are the answers to fill in the blanks:
- A graph
- slopes
- a constant
- non-constant
- accelerating
- decelerating
So the complete sentences would read:
A graph is essentially many line segments with different slopes at each segment.
While a straight line shows a constant rate of change, a curved line indicates that the rate of change is non-constant.
A curved line suggests that the object's speed is changing over time—it could be accelerating (the curve gets steeper) or decelerating (the curve becomes less steep).
