hi altime,

area is 12 means 1/2 * x* y= 12 --->>> x*y= 24 (Dont have question like why area should be -ve??? because we will take the no of units from orgin , not the nuemeric values)

we have x as 4 y should be either 6 or -6

Since it has a positive slope it will pass through first and 3rd quadrant.

so Answer is -6

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
