A football coach paces back and forth along the sidelines during a close rivalry game. the diagram below shows several of the coach's positions and various times. At each marked positions, the coach makes a u-turn and moves the opposite direction. In other words, the coach moves from position a to b to c to d. (Could someone please explain this. Thank you)

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.

They all deal with hard evidence(scientific)
