A coordinate plane is divided into these sections.
(HINT: there are 4 of them)
quadrants
What is the ordered pair for point E ?
(-5,-6)
What happens when you reflect a coordinate point across an axis? Given an example.
The coordinates of the point change to the opposites, depending on which axis.
For example, when reflecting (x, y) across the x-axis, the new point is (x, -y). The x-coordinate stays the same and the y-coordinate changes to the opposite.
Find the horizontal or vertical distance between the two points.

The distance between the two points is 1 unit
Point Z is located 8 units to the right and 2 units up from the origin. Which ordered pair represents the coordinates of point Z?
(8,2)
The horizontal axis on the coordinate plane.
x-axis
What is the ordered pair for point D?
(5, -6)
A reflection across the x-axis changes which coordinate? (x- or y-coordinate)
y-coordinate
Find the horizontal or vertical distance between the two points.

The distance between the two points is 3.5 units
Mr. Lewis plotted a point to represent the ordered pair (4,3). Which describes the process he used to graph this point on a coordinate plane?
He located the point 4 units to the right of the origin and 3 units up.
When plotting an ordered pair, you must always start at what point on a coordinate plane?
the origin
What is the order pair for point C?
(0, 0) (the origin)
What is the symbol for a reflection of a new point (prime notation)?
An apostrophe '
Find the horizontal or vertical distance between the two points.

The distance between the two points is 2 units
The point Z’(–5, 3) is the result of reflecting Z(5, 3) in the coordinate plane. Identify the axis across which the point was reflected.

A groundskeeper is preparing a field for a soccer match. He begins by setting the first corner at (15, 10). What is the location of the corner that reflects across the y-axis?
(-15, 10)
The 2nd number in an ordered pair, locating a point on the y-axis of a coordinate plane.
y-coordinate
What is the ordered pair for point B?
( -4, -4)
