Brenda is building a square fence. She places a fence post at (─3,2). What is the location of the post (in which quadrant) that
Fynjy0 [20]

The post is on the first quadrant at the coordinates (3, 2).

Step-by-step explanation:

Step 1; First we need to determine which quadrant the point (-3, 2) is on. The coordinate has a negative value of x which denotes it could be located on either the second or third quadrant. The y coordinate has a positive value so out of the second and third quadrant, it is located in the second quadrant.

Step 2; The fence post is reflected over the y-axis which means the coordinate values remain the same but the symbols are in accordance with the first quadrant. In the first quadrant, both x coordinates and the y coordinates are positive. So the co-ordinate for the reflected fence post is    (3, 2).

Marianna [84]

Hello! :)

2x + 3y + −3y = q + −3y Add -3y to both sides

2x = q − 3y

2x/2 = q-3y/2 Divide both sides by 2

x = 1/2q + -3/2 y (ANSWER)
