Whats an exponent and how is it used an mathematics

 a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression

Step-by-step explanation:

for example

10  x 10 = 100

to simplify this you put a small 2 on the top right corner of the number 10

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

definitely a. the others have almost all data points on one side of the line.
