Do you have to take physics to graduate high school?

Usually, you have to take two years of physical sciences with lab. It doesn't have to be physics, it can be chemistry or biology. 

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.
