In a velocity vs. time graph, what does a slope of zero indicate about the car's motion?

• The car is speeding up

• The car is slowing down

• The car is moving at a constant speed

• The car is stationary

What is the y-intercept of a velocity vs. time graph when using the equation v = v₀ + at?

• Acceleration

• Initial velocity

• Final velocity

• Time

Why should you never see a graph with negative time on an axis?

• Time cannot be negative.

• It is possible but not common.

• Negative time is used in advanced physics.

• It is a convention to avoid confusion.
