Find the

coordinates

Can you write down

the coordinates of

points A, B, C, and

D? Remember the

x coordinate is

written first, then

the y coordinate.

Grids and maps

One of the most common ways

we use coordinates on a grid is

to find locations on a map. Most

maps are drawn with a

coordinate grid.

Plotting points using

coordinates

We can also use coordinates to place, or plot,

points accurately onto a grid.

Next, we count two squares

up the y axis.

To plot the coordinates (4, 2),

we first count four squares

along the x axis.

Now we mark the point we

have reached with a dot.

The origin's coordinates

are (0, 0)

We sometimes write the

coordinates next to the point

Marking a specific

place on a grid is

called plotting a point.
