A coordinate grid from negative 2 to 0 to positive 2 is drawn. There are three grid lines between a whole unit on the grid. Part A: Which point represents the origin? Part B: Starting from the origin, explain how to plot the following three points accurately: (1, −1) (−1, 1.25) (−2, fraction 3 over 4)

Froggy2324:

please help me

Froggy2324:

there are 64 little squares in each quadrant

mhanifa:

Do you have the picture?

Froggy2324:

i have one but i cant put it on here

mhanifa:

For part A, do you know what is the origin. What is its coordinates?

Froggy2324:

I dont know the origin but the coordinates are at the bottom of the question

mhanifa:

The origin is the center of the grid, with coordinates (0, 0), do you have it in the picture?

Froggy2324:

yes but there is only 1 zero

mhanifa:

Ok, that's the one. Its Part A. For Part B, do you know how to plot the points?

Froggy2324:

yes

mhanifa:

Then it should be easy for you. Let's practice point (1, -1), how do you plot this?

Froggy2324:

put it in the 2nd quadrant then find the one on the right side take it to the left and down to the -1

mhanifa:

Can you sketch it here, not too clear to me.

Froggy2324:

mhanifa:

Thanks but this is incorrect.

Froggy2324:

?

mhanifa:

Pairs of coordinates represent (x, y) the first number, the x-coordinate represents the distance left or right from the origin. The second number, the y-coordinate represents the distance up or down from the origin.

mhanifa:

To plot (1, -1) you go right 1 unit and then down 1 unit (down as it is negative)

mhanifa:

Let me know if its clear.

Froggy2324:

I dont understand

mhanifa:

This is opposite of what you did to plot the point. First number means left or right, the second number means up or down.

Froggy2324:

oh ok

mhanifa:

Froggy2324:

I get it now

mhanifa:

Can you do the other points?

Froggy2324:

I think so

mhanifa:

Let me know if any difficulties and good luck.

Froggy2324:

Froggy2324:

does it go like that since the first number is negative?

mhanifa:

Yes for the second point. You can plot this more accurately on the grid. Its exactly 1 unit left and 1 and quarter unit up.

Froggy2324:

I know, that's what I tried to do.

mhanifa:

I think you are done. Good job.

Froggy2324:

Thank you so much

mhanifa:

You are welcome!
