Hello, Experts. Please help explain what's the best approach to solving this problem. Thanks!
Hi lionsshare,
I think you need to study basics of coordinate geometry. This question only tests your ability to read the coordinates of a point.
In a coordinate plane, a point can be fixed with the help of two dimensions, called coordinates. x-coordinate tells how far horizontally a point is there from the origin, while y-coordinate tells how far (up/down) vertically a point is there from the origin.
Thus, point V has two coordinates: x and y. The standard convention is to write x-coordinate and then y-coordinate: (x, y).
We see that point V is horizontally 7 points far towards the positive direction of the x-axis (Moving towards right from the origin is a positive direction while moving towards left is negative). From the markings on the x-axis, we find that the x-coordinate is 7 (positive 7).
Similarly, we see that point V is vertically 5 points down towards the negative direction of the y-axis (Moving up from the origin is a positive direction while moving down is negative). From the markings on the y-axis, we find that the y-coordinate is -5 (negative 5).
Thus, the coordinates of point V are (7, -5).
The correct answer:
E
Hope this helps!
