Firstly you draw your x and y axis. The x-axis is the horizontal line and the y-axis is the vertical line. The coordinates of a point help you understand its location from the centre, which on the x and y axis is the point where the two lines meet. You then need to count how many steps to the left or right a point is from the centre which gives you the x-coordinate, and then how many steps up or down a point is from the centre which gives the y-coordinate. The location is written as (x-coordinate, y-coordinate).
