What is the horizontal number line on a coordinate plane and wouldthis be the length or the width when finding area
x-axis and length
Which ordered pair represents a point 3 left and 5 down?
(-3,-5)
What is the distance between the points (7,9) and (-4,9)? Is it vertical or horizontal?
11 and vertical
What is the rule for reflecting points across the x and y axis
If reflected across the X-axis your X coordinate stays the same and you Y coordinate becomes the opposite.
If reflected across the Y-axis your Y coordinate stays the same and you X coordinate becomes the opposite.

Three corners of a rectangular playground fence are:
A (-4, 5)
B (6, 5)
C (6, -2)
Find the coordinates of the fourth corner.
(-4,-2)
A point P is located at (5, -2).
First, reflect the point across the x-axis.
Then reflect the new point across the y-axis.
Question:
What are the final coordinates?
(-5,2)
A rectangular exhibit floor has vertices
(-3, -1)
(-3, 4)
(5, 4)
(5, -1)
Each unit represents 2 feet.
Find the area of the exhibit floor in square feet.

A student says the missing vertex of a rectangle with points
(2, 7)
(2, 3)
(8, 3)
is (8, 7) because “you just flip the numbers.”
Question:
Is the student correct? Explain why or why not.
Yes. The rectangle must keep the same x-values and y-values, so the missing vertex is (8,7).
What quadrant is the point (9,0) located
Not a quadrant, the x-axis
A bridge runs along the coordinate plane between (-6, 3) and (4, 3).
Each unit represents 10 feet.
How long is the bridge?
100 Feet
