in which quadrant is the point negative seven comma seven located so let's just review what a quadrant is a quadrant are each of the four sections of the coordinate plane and when we talk about the sections we're talking about the sections as divided by the coordinate axes so this right here is the x-axis and this up-down axis is the y-axis and you can see it divides the coordinate plane into four sections we call each of these sections quadrants this one over here where both the X values and the y values are positive we call the first quadrant and we use the Roman numeral one then if we kind of move counterclockwise around the coordinate plane this quadrant where the X values are negative and the Y values are positive we call this the second quadrant we call this the second I could write it we call this the second quadrant second quadrant then we go down here where both the X values are negative and the Y values are negative we call this the third quadrant once again using Roman numerals then finally the quadrant where the X values are positive but the Y values are negative we call this the fourth quadrant so let's see which quadrant the point negative seven comma seven is located so there's two ways to think about it you could just say look we have a negative x value our x value is negative so we're going to move to the left so we're going to be on this side we're going to be on this side right here of the coordinate plane so we're either just by the fact that the x value is negative we're going to be either in the second or the third quadrant now we know that the Y value is positive we know that the Y value is positive so if the x value is negative and the Y value is positive we're going to land someplace right over here in the second quadrant the other way to think about it is you could literally just plot this point and see that it falls in the second quadrant so let's do that if X is negative seven so that's negative one negative two negative three negative four negative five negative six negative seven do I do that right one two three four five six seven so this is X is negative seven and then we have to go up seven because Y is equal to positive seven so one two three four five six seven so the point negative seven comma seven is right right over here clearly lies in the second quadrant
