Front

What are the coordinates of point F?

Back

(-4, 1)

Front

What are the coordinates of point H?

Back

(-5, -4)

Front

The points could be in Quadrants II and IV of the coordinate plane. True or False?

Back

False

Front

What are the coordinates of point G?

Back

(3, -2)

Front

In which quadrant is the REFLECTION of point P in the coordinate plane?

Back

Quadrant II

Front

What is the definition of coordinates in a coordinate plane?

Back

Coordinates are a set of values that show an exact position on a two-dimensional plane, typically represented as (x, y).

Front

What are the four quadrants of a coordinate plane?

Back

Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

How do you identify the quadrant of a point with coordinates (x, y)?

Back

If x is positive and y is positive, it's in Quadrant I; if x is negative and y is positive, it's in Quadrant II; if x is negative and y is negative, it's in Quadrant III; if x is positive and y is negative, it's in Quadrant IV.

Front

What is the reflection of a point across the y-axis?

Back

The reflection of a point (x, y) across the y-axis is (-x, y).

Front

What is the reflection of a point across the x-axis?

Back

The reflection of a point (x, y) across the x-axis is (x, -y).
