Front

How many quadrants are in a coordinate plane?

Back

4

Front

What is the distance formula used to find the distance between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What are the coordinates of the origin in a coordinate plane?

Back

(0, 0)

Front

What does a reflection over the x-axis do to the coordinates of a point (x, y)?

Back

It changes the y-coordinate to its opposite: (x, -y)

Front

What does a reflection over the y-axis do to the coordinates of a point (x, y)?

Back

It changes the x-coordinate to its opposite: (-x, y)

Front

If a point is reflected over both axes, what happens to its coordinates?

Back

The coordinates change to (-x, -y)

Front

What is the coordinate of point A if it is located 4 units right and 3 units up from the origin?

Back

(4, 3)

Front

What is the distance between the points (1, 2) and (4, 6)?

Back

5

Front

What is the reflection of the point (3, -4) over the y-axis?

Back
