Coordinate Plane

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), used to locate points using ordered pairs.

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

Which quadrant contains the point (2, 5)?

Back

Quadrant I.

Front

What is an ordered pair?

Back

A pair of numbers (x, y) that represent a point's position on the coordinate plane.

Front

What does the x-axis represent?

Back

The horizontal number line in the coordinate plane.

Front

What does the y-axis represent?

Back

The vertical number line in the coordinate plane.

Front

What is the origin in the coordinate plane?

Back

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

Front

How do you identify the coordinates of a point?

Back

By using the format (x, y), where x is the horizontal distance from the origin and y is the vertical distance.

Front

What is the equation of a line with a slope of 1 that passes through the origin?

Back

y = x.

Front

What is the slope of a line?

Back

The ratio of the vertical change to the horizontal change between two points on the line.
