What number is represented by point B?
Which point represents the number 2?

-1, c

Step-by-step explanation:

Each dot represents 1.  

0 - 1 = -1

As labeled, c represents 2.

Point B: -1

2: Point C

Step-by-step explanation:

On a number line, going the left is subtracting one and going right is adding one. Point B is between -2 and 0 and one space before 0, 0-1= -1 so point B is -1. On the number line, the number is, the dot 2 spaces to the right of 0. On top of 2 is C so point c represents the number 2.

the answer to this is a. a^2 + b^2 = c^2
