Write the ordered pair for point D.

Short Answer

Expert verified

The ordered pair that names each points of D is (鈭�1,鈭�4).

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, -,+.
  • 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 pointD, observe that D is in third Quadrant.

To plot the graph of the point D, first move 1 unit to the left starting from origin and then move 4 units down.

Thus, the point is D (鈭�1,鈭�4).

03

Step 3. State the conclusion.

Since, the point D is in Quadrant III, therefore, the required coordinates of point D is (鈭�1,鈭�4).
