we're asked to use the reflect tool to find the image of quadrilateral PQRS that's quote this quadrilateral right over here for a reflection over the line y is equal to X plus 2 all right so let's use the reflect tools let me scroll down so let me click on reflect it brings up this tool and I want to reflect across the line y is equal to X plus 2 so let me move this so it has so it is the line y equals x plus 2 and to think about it let's see it's going to have it's going to have a slope of 1 the coefficient on the X term is 1 so it's going to have a slope of 1 so let me see if I can give this a slope of 1 is this a slope of 1 we put it a little bit yep that looks like a slope of 1 as the line moves one to the right we go from one point of the line to the other you have to go one to the right and one up or two to the right and two up however much you move to the right in the X direction you have to move that same amount in the vertical direction so now it has a slope of 1 and the y-intercept is going to be the point x equals 0 y equals 2 we see that right over here when X is equal to 0 Y is going to be equal to 2 so let me move this so we see and we now go through that point when x is equal to 0 Y is equal to 2 and now we just need to reflect we need to reflect PQRS this this quadrilateral over this line so let's do that there you go we did it the things the point like Point s right over here that was to the top and left of the line its reflection if the the corresponding point in the image is now to the right and the bottom of the line the things that were to the right and the bottom of our line like point P it's the corresponding point in the reflection is now on the other side of the line so there you go I think we're done and we got it right
