Chapter 3: Q7. (page 151)

Write the ordered pair for point A.

Short Answer

Expert verified

The ordered pair that names each points of A is (3,鈭�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, +,+.
  • In Quadrant II, first number is negative and second is positive, that is, 鈭�,+.
  • In Quadrant III, both the coordinates of ordered pair are negative, that is, 鈭�,鈭�.
  • In Quadrant IV, first point is positive and second is negative, that is, +,鈭�.
02

Step 2. Plot the point.

In order to plot the pointA, observe that A is in fourth Quadrant.

To plot the graph of the point A, first move 3 units to the right starting from origin and then move 1 unit down.

Thus, the point is A(3,鈭�1).

03

Step 3. State the conclusion.

Since, the pointA is in QuadrantIV, therefore, the required coordinates of pointA is (3,鈭�1).
