Question

In 11 and 12, use the map in Example 2 and write

the landmark located at each ordered pair.
11. (0.5, 0)
12. (3/4,-1/2)

Answer 1

11. Ellipse

12. Washington Monument

Explanation:

You are being asked to locate points on a graph, given an ordered pair.

The first number of the pair is the x-coordinate, the distance to the right of the y-axis. The second number of the pair is the y-coordinate, the distance up from the x-axis. When it is negative, the point will be found below the x-axis.

On this coordinate plane, there are 4 grid lines between integer labels, so each grid line stands for 1/4 unit, or 0.25 units.

__

11.

(0.5, 0) will be 2 grid lines to the right of the y-axis, and on the x-axis. That location is labeled Ellipse.

__

12.

(3/4, -1/2) will be 3 grid lines to the right of the y-axis, and 2 grid lines below the x-axis. That location is labeled Washington Monument.
