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).

How do you find the distance between two points on the same horizontal line?

Back

Subtract the x-coordinates and take the absolute value. Example: Distance between (-3,5) and (7,5) is |7 - (-3)| = 10.

What is the formula for the perimeter of a square?

Back

Perimeter = 4 × side length. Example: For a square with side length 6, Perimeter = 4 × 6 = 24.

What happens to the coordinates of a point when it is reflected over the x-axis?

Back

The y-coordinate changes sign. Example: (4, 9) reflected over the x-axis becomes (4, -9).

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

Back

Check the signs of x and y: (+, +) = 1st, (-, +) = 2nd, (-, -) = 3rd, (+, -) = 4th.
