Grade 7: Coordinate Graphing Flashcard

Front

What are coordinates?

Back

Coordinates are a set of values that show an exact position on a graph, typically represented as (x, y).

Front

What is the x-axis?

Back

The x-axis is the horizontal line on a graph where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical line on a graph where the x-coordinate is zero.

Front

What are the four quadrants in a coordinate plane?

Back

Quadrant 1: (+, +), Quadrant 2: (-, +), Quadrant 3: (-, -), Quadrant 4: (+, -).

Front

How do you identify the quadrant of a point?

Back

The quadrant is determined by the signs of the x and y coordinates: (+, +) is Quadrant 1, (-, +) is Quadrant 2, (-, -) is Quadrant 3, and (+, -) is Quadrant 4.

Front

What does the point (0, 0) represent?

Back

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

Front

What is the significance of the x-coordinate?

Back

The x-coordinate indicates the horizontal position of a point on the graph.

Front

What is the significance of the y-coordinate?

Back

The y-coordinate indicates the vertical position of a point on the graph.

Front

How do you plot a point on a coordinate plane?

Back

To plot a point, start at the origin (0, 0), move along the x-axis to the x-coordinate, and then move vertically to the y-coordinate.

Front

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

Back

The distance formula is d = √((x2 - x1)² + (y2 - y1)²).
