6. A train travels from station X (1, 2) to station Y (5, 10). What does the slope of the line tell you about the train's speed?

• The slope indicates the train is accelerating rapidly.

• The slope shows the train is moving backwards.

• The slope of the line indicates the train's speed is consistent, moving 2 units vertically for every 1 unit horizontally.

• The slope represents the distance traveled by the train.
