Distance on a Coordinate Plane

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on the coordinate plane, written as (x, y).

Front

What does the x-axis represent on a coordinate plane?

Back

The x-axis is the horizontal number line on a coordinate plane.

Front

What does the y-axis represent on a coordinate plane?

Back

The y-axis is the vertical number line on a coordinate plane.

Front

How many quadrants are there in a coordinate plane?

Back

There are four quadrants in a coordinate plane.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0, 0).

Front

If point A is at (2, 3) and point B is at (5, 7), what is the distance between them?

Back

Distance = √((5 - 2)² + (7 - 3)²) = √(9 + 16) = √25 = 5.

Front

What is the area of a rectangle with a length of 5 units and a width of 4 units?

Back

Area = length × width = 5 × 4 = 20 square units.

Front

What are the coordinates of the point located in the second quadrant?

Back

Coordinates in the second quadrant have a negative x-value and a positive y-value.

Front

What is the formula to calculate the area of a triangle?

Back

Area = 1/2 × base × height.
