Chapter SR13, Problem 22P

Solution

Give the coordinates and quadrant or axis of the point.

B(-1,-2).

Third Quadrant.

Given:

The given point is B.

  

Concept Used:

• Start at the origin.
• If x-coordinate is positive move right from origin and if x-coordinate is negative move left from origin.
• If y-coordinate is positive move up from origin and if y-coordinate is negative move down from origin.

Calculation:

The given point is B.

  

From the graph −

The coordinate of point B is (-1,-2).

And Quadrant of B is third Quadrant.
