First solution:

Calculate the marks, pay attention to the sign and find the coordinates. There are 7 marks on the X axis in the positive direction, so the x-coordinate of point V is 7. There are 5 marks on the Y axis in the negative direction, so the y-coordinate of point V is -5. Thus the coordinates (x,y) of point V are (7,-5).

Second solution:

Find the signs of the V coordinates. Point V belongs to the IV quadrant and has a positive x-coordinate and a negative y-coordinate. There is only 1 answer with such properties.
