Chapter 3: Q8. (page 151)

Write the ordered pair for point B.

Short Answer

Expert verified

The ordered pair that names each points of B is (−3,1).

Step by step solution

01

Step 1. State the concept for finding the coordinates of a point.

In rectangular coordinate system any point be in the form of x,y.

  • In Quadrant I, both the coordinates of ordered pair are positive, that is, width="42" height="19" role="math">+,+.
  • In Quadrant II, first number is negative and second is positive, that is, -,+.
  • In Quadrant III, both the coordinates of ordered pair are negative, that is, -,-.
  • In Quadrant IV, first point is positive and second is negative, that is, +,-.
02

Step 2. Plot the point.

In order to plot the pointB, observe that B is in second Quadrant.

To plot the graph of the point B, first move 3 units to the left starting from origin and then move 1 unit up.

Thus, the point is B(−3,1).

03

Step 3. State the conclusion.

Since, the pointB is in QuadrantII, therefore, the required coordinates of pointB is (−3,1).
