hint: plot each point for each answer choice in show your work and draw an line through those points to see if the line is a line of symmetry (aka line of reflection)

did it flip? did it turn? did it slide?

1

meaning, which axis is the line of symmetry?

1

remember this from the back of page 58??? remember to use desmos to see where the line y=-x would be...

1

remember that x=2 means a vertical (up and down) line thru 2 on the x-axis...

remember that y=5 means a horizontial (left to right) line thru 5 on the y-axis...

1

think about it...for which line(s) could you 'fold' this on and all of the info be the same on both sides of the line.

1

Create imaginary lines for each figure...or which one will 4

Which describes a translation of figure A?

1

If the image above is translated 3 units left and 2 units up, what would be the new location of point A?

If the image above is translated 3 units left and 2 units up, what would be the new location of point B?
