Unit 3 Test Review

Front

What is a coordinate grid?

Back

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

Front

What does the point (2, 3) represent on a coordinate grid?

Back

The point (2, 3) represents a location that is 2 units to the right of the origin (0, 0) and 3 units up.

Front

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

Back

To find the distance between two points (x1, y1) and (x2, y2), use the formula: Distance = |y2 - y1| + |x2 - x1|.

Front

What is the distance between the points (6, 9) and (6, -5)?

Back

The distance is 14 units.

Front

What is the distance between the points (1, 2) and (1, -3)?

Back

The distance is 5 units.

Front

How do you plot the point (4, -12) on a coordinate grid?

Back

To plot (4, -12), move 4 units to the right and 12 units down from the origin.

Front

What is the significance of the x-coordinate in a point (x, y)?

Back

The x-coordinate indicates the horizontal position of the point on the coordinate grid.

Front

What is the significance of the y-coordinate in a point (x, y)?

Back

The y-coordinate indicates the vertical position of the point on the coordinate grid.

Front

What does it mean if two points have the same x-coordinate?

Back

If two points have the same x-coordinate, they lie on a vertical line.

Front

What does it mean if two points have the same y-coordinate?

Back

If two points have the same y-coordinate, they lie on a horizontal line.
