Question

determine the quadrants in which (x,y) is located so that the condition(s) is (are) satisfied:

(x,-y) is in the second quadrant

Answer 1

(x, -y) is the 4th quadrant. The reason for this is because you can look at the four quadrants and understand quickly. the first quadrant is the right-top. It is positive x, positive y.
The second quadrant is negative x, positive y and top-left.
The third quadrant is negative x, negative y and bottom-left.
The fourth quadrant is positive x, negative y, and bottom right.

Hope this helps. If it does, please choose good answer.

Answer 2

thanks, but for some reason, the back of my book tells me it's quadrant 3. any idea why?? or else I would have put your answer.

Answer 3

Q1 is (x,y) Q2 is (-x,y), Q3 is (-x,-y), Q4 is (x,-y)

Answer 4

Are you sure that you typed it in here correct. Make a graph and take a look at it. I will make one in paint and attach in a minit.

Answer 5

yep, that's right. the next question (even though i don't have to do it) says (-x,y) is in the fourth quadrant. which doesn't make sense either. my precal book is about to go out the window.

Answer 6

See if this helps out.

Answer 7
