What is the constant slope?
Space and AstronomyFor example, a small slope means a small velocity; a negative slope means a negative velocity; a constant slope (straight line) means a constant velocity; a changing slope (curved line) means a changing velocity. How do you find a constant slope? The slope equals the rise divided by the run: . You can determine the
