Coordinate Graphing

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).

Front

What are the four quadrants of the coordinate plane?

Back

Quadrant I (x > 0, y > 0), Quadrant II (x < 0, y > 0), Quadrant III (x < 0, y < 0), Quadrant IV (x > 0, y < 0).

Front

What does an ordered pair represent?

Back

A pair of numbers (x, y) that indicate a specific point on the coordinate plane.

Front

What is the X-axis?

Back

The horizontal axis on the coordinate plane where the y-coordinate is zero.

Front

What is the Y-axis?

Back

The vertical axis on the coordinate plane where the x-coordinate is zero.

Front

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

Back

Determine the signs of x and y: both positive in Quadrant I, x negative and y positive in Quadrant II, both negative in Quadrant III, and x positive and y negative in Quadrant IV.

Front

What is the origin in the coordinate plane?

Back

The point (0, 0) where the x-axis and y-axis intersect.

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What does it mean for points to be collinear?

Back

Points that lie on the same straight line.

Front

What is the slope of a line?

Back

The ratio of the rise (change in y) to the run (change in x) between two points on the line.
