Remember: The signs of a pair tell its corner. A mirror changes the signs.
Name the places
1
Which pair names point D? Say across first, then up.
(4, 1)(1, −4)(−1, 4)(−4, 1)
2
What is the x-number of point E?
3
Point K is at (−2, 4). Which corner is it in?
Quadrant 4, bottom rightQuadrant 2, top leftQuadrant 1, top rightQuadrant 3, bottom left
4
The point (−4, 3) is in the bottom left corner.
TrueFalse
5
Join each point to the corner it is in.
1(−2, 5)
2(2, 5)
3(2, −5)
4(−2, −5)

Btop left
Ctop right
Dbottom right
6
Which graph shows the point (3, −2)?
Graph 1Graph 2Graph 3
7
A mirror lies along the y-axis. Which point is the mirror image of A?
Point PPoint QPoint R
8
Point A is at (4, −3). Its mirror image across the x-axis is at (4, ). What is the new y-number?
9
Which mirror turns A into B?
The x-axisBoth axesThe y-axis
10
Point A is at (−4, 1). Which point is its mirror image across both axes?
(4, −1)(−4, −1)(4, 1)
11
The point (−3, −5) is in the same corner as (−1, −1).
TrueFalse
12
Number the steps to mark (−2, 5).
Put your pencil on the origin, (0, 0)
Slide 5 steps up, because y is 5
Slide 2 steps left, because x is −2
Make a dot and write the pair
13
P is at (−2, 4) and Q is at (−2, −3). How many units apart are they?
14
Write the pair for the mirror image of (5, −2) across the y-axis. Tell how you know.
