I did A Lab in science where I had a Small hotwheels car and started and 6 books and made a ramp. I then timed how long it took the car to go 2 meters from the ramp. after each trial I added one more book to make the slope higher. The car stayed the same and the higher the slope/ramp, the faster it went.
I'm suppose to make a scatter plot of my data. Plotting the independant variable on the x-axis and the dependant variable on the y-axis, except I need a little help on deciding what the dependant and independant variables are.
