enVision Math 6 Topic 2-Coordinate Plane Review

Front

What is the coordinate plane?

Back

A two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to locate points using ordered pairs (x, y).

Front

What does each unit represent on a coordinate map?

Back

Each unit represents 1 block.

Front

How do you find the distance between two points on a coordinate plane?

Back

Use the distance formula: Distance = |y2 - y1| for vertical movement or |x2 - x1| for horizontal movement.

Front

What happens to the y-coordinate when a point is reflected over the x-axis?

Back

The y-coordinate changes its sign (positive becomes negative and vice versa).

Front

What is the ordered pair for a point in Quadrant I?

Back

An ordered pair in Quadrant I has both x and y coordinates positive, e.g., (3, 2).

Front

What is the ordered pair for a point in Quadrant II?

Back

An ordered pair in Quadrant II has a negative x-coordinate and a positive y-coordinate, e.g., (-3, 2).

Front

What is the ordered pair for a point in Quadrant III?

Back

An ordered pair in Quadrant III has both x and y coordinates negative, e.g., (-3, -2).

Front

What is the ordered pair for a point in Quadrant IV?

Back

An ordered pair in Quadrant IV has a positive x-coordinate and a negative y-coordinate, e.g., (3, -2).

Front

If point A is at (-6, -1), what is its reflection across the x-axis?

Back

The reflection of A (-6, -1) across the x-axis is (-6, 1).

Front

What is the x-axis?

Back

The horizontal line on the coordinate plane where y = 0.
