plot for common negative one and select the quadrant in which the point lies so for the first number in our ordered pair that's our x-coordinate that says how far to move in the in the horizontal or the x-direction it's a positive 4 so I'm going to go 4 to the right and then the second coordinate says what do we do in the vertical direction or in the Y direction it's a negative 1 since it's negative we're going to go down and it's a negative 1 so we're going to go down 1 so that right over there is the point 4 comma negative 1 so I've plotted it but now I have to select which quadrant the point lies in and this is just a naming convention this is the first quadrant this is the second quadrant this is the third quadrant and this is the fourth quadrant so the point lies in the fourth quadrant quadrant 4 and I guess you have to know your Roman numerals a little bit to know that that's the foot that's representing quadrant 4 let's do a couple more of these plot eight comma negative 4 and select the quadrant in which the point lies well my x-coordinate is 8 so I move 8 or go 8 in the positive x-direction and then my y-coordinate is negative 4 so I go four down and this is sitting again in no not the first not the second not the third but the fourth quadrant in quadrant four let's do one more of these hopefully we get a different quadrant so we want to plot the point negative 5 comma 5 so now my x-coordinate is negative its negative 5 so I'm going to move to the left in the x-direction so I go to negative 5 and my y coordinate is positive so I go up 5 so negative 5 comma 5 and this is sitting not in the first quadrant but the second quadrant and of course this is the third and the fourth sitting in the second quadrant check answer and we got it right
