Take a look at the figure. What are the coordinates of the point labeled A in the graph shown? A. (2, 2) B. (–2, 2) C. (2, –2) D
vodka [1.7K]
Hello. There was no figure to look at so I plotted all of these points for you. Which one looks like the figure to you? That will be your answer. 

Remember, you plot the first number first, which will be along the X axis on a graph. Thats the line that runs right to left. 

Then you plot the second number, which will be along the Y axis on a graph. 
Thats the line that runs up and down. 

If you go down or to the left, you will have a negative point. If you go up or to the right you will have a positive point.
