What point names the ordered pair (–2, 8)?

a.

a

b.

b

c.

c

d.

d

Here, we have a formula.

(-2, 8) is not some random two numbers. It stands for the x-coordinate and y-coordinate, where:

(x, y) = (-2, 8)          OR            x = -2 and y = 8

On the coordinate-plane, commonly known as a graph, the big horizontal line is known as x. The big vertical line is known as y. 

Each little dash on the line represents a number. For example, A would be (2, 8) since you go right 2 "x" units and up 2 "y" units.

Thus for (-2, 8) it resides at point C, since you go left 2 "x" units and right 8 "y" units.

Remember, x is left and right, and y is up and down.
