Coordinates

Front

What are the coordinates of a point in a 2D plane?

Back

Coordinates are a pair of numbers (x, y) that define the position of a point on a 2D plane.

Front

What is the Y-axis in a coordinate plane?

Back

The Y-axis is the vertical line on a coordinate plane where the x-coordinate is 0.

Front

What is the X-axis in a coordinate plane?

Back

The X-axis is the horizontal line on a coordinate plane where the y-coordinate is 0.

Front

In an ordered pair (x, y), which coordinate is the X coordinate?

Back

The X coordinate is the first number in the ordered pair.

Front

In an ordered pair (x, y), which coordinate is the Y coordinate?

Back

The Y coordinate is the second number in the ordered pair.

Front

What does the term 'origin' refer to in a coordinate plane?

Back

The origin is the point (0, 0) where the X-axis and Y-axis intersect.

Front

How do you plot a point with coordinates (3, 4) on a coordinate plane?

Back

Start at the origin (0, 0), move 3 units to the right (positive x-direction), and then move 4 units up (positive y-direction).

Front

What is the distance formula used for in coordinate geometry?

Back

The distance formula calculates the distance between two points (x1, y1) and (x2, y2) as d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the midpoint formula in coordinate geometry?

Back

The midpoint formula finds the midpoint M between two points (x1, y1) and (x2, y2) as M = ((x1 + x2)/2, (y1 + y2)/2).

Front

What is the slope of a line in coordinate geometry?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x (rise/run).
