How do you plot the points in a coordinate plane; A(9, -2)?

Hi, this question is basically talking about placing a point in a coordinate plane (which you learn in grade 7, depending where you live).

Explanation:

So, as you know the first number in the brackets is the vertical (left to right) axis (or line, you could call it). The positive numbers in a coordinate plane in a vertical axis go to the right.

graph{x0 [-10, 10 -5, 5]}

I hope that you can find the middle line thats in blue, the one that goes across the graph. You can see the #10# in the graph. So, I sincerely hope you can count. You'll count 9 spaces to the right from the 0. Put a point or note that down.

Now, look at the second number in the brackets, which is #-2#.
In the horizontal axis (line), the positive numbers go upwards and the negative numbers go downwards. Since the number #-2# is negative, it should go down two spaces.

Heres the sometimes tricky part for people. So you move down the 9 (the first point you put down) by a bit lower (#-2#) (sorry if I'm bad at explaining this part). You'll eventually or somehow get to a point below 0 horizontally and to the right 9 spaces.

Hope that helped!

Thanks for reading.
