Answer 1

With what?

Answer 2

First it is important to see that x = -3 is a vertical line at x = -3



Since the point will be reflected across that line..we will end up over here:



Notice right away that the 'y' value does not change since it is just going father ro the left of the graph...not up or down

Answer 3

So if before...the coordinate of U is (-1, -3)

We know that -3 in the y-coordinate will be the same no matter what..so we have

U' = (? , -3)

How do we figure out the new x-coordinate?

Answer 4

Well...since we are reflecting across the line x = -3

And the original point was at x = -1 that is a 2 space difference...

After a reflection, it will still be the same distance from the line...2 spaces...but in this case...farther to the left..

So if we start at x = -1 flip it over x = -3 we end up 2 more spaces away from -3...

x = ?

Answer 5

-5

Answer 6

Right...

so the new coordinate will be (-5 , -3)
