• By the slope of the line

• By the color of the line

• By the position of the line relative to the time axis

What does a horizontal line on a velocity-time graph indicate?

• Constant acceleration

• Changing velocity

• Negative acceleration

• Constant velocity

What is the formula for calculating the slope of a line on a velocity-time graph?

• Sum of velocity and time

• Change in time divided by change in velocity

• Product of velocity and time

• Change in velocity divided by change in time

What does a positive slope on a velocity-time graph indicate?

• Positive acceleration

• Constant velocity
