The coordinate of each point is a set of two number in a round bracket.
The first number is the x-coordinate of that point. That's the place of the point on the x-axis.
The second number is the y-coordinate of that point. That's the place of the point on the y-axis.
Taking point A (9, 7) as an example.
x-coordinate of A: 9.
y-coordinate of A: 7.
The x-axis is the horizontal axis. Find the tick with number "9" on the horizontal x-axis. Draw a vertical line through that tick. The x-coordinate of all points on that vertical line is 9.
The y-axis is the vertical axis. Find the tick with number "7" on the vertical y-axis. Draw a horizontal line through that tick. The y-coordinate of all points on that horizontal line is 7.
The two lines should intersect at some point on the grid. The x-coordinate of the place where they intersect is 9, and the y-coordinate will be 7. The intersect is the position of point A.
Repeat these steps for the rest of the four points. See if every single point is in their place.
