A ball is dropped from a height h and falls the last half of its distance in 4 seconds. How long does the ball fall? From what height is the ball originally dropped?

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
