Write the ordered pair for each point.

B

Short Answer

Expert verified

The ordered pair for point Bis (0,3).

Step by step solution

01

Step 1. Observe the figure.

From the figure, it can be observed that it is thex-y plane with several coordinatesA,B,C,D,E, andF marked on it.

02

Step 2. Define the coordinate of a point.

Coordinate or an ordered pair x,y of a point is a pair of numbers; that is, a number on the x-axis called an x-coordinate, and a number on the y-axis called a y-coordinate.

03

Step 3. Name the coordinates of the point B.

Steps to find the coordinate of point Bare:

  • PointB is 0 units away from the origin on xaxis. Thus, the x-coordinate is 0.
  • Then the point Bis 3 units away from the origin on the positive yaxis. Thus, the y-coordinate is 3.

From the given graph,

Therefore, the coordinates of point Bis 0,3.
