Graphing

Front

What is an ordered pair?

Back

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

Front

What does the x-axis represent on a graph?

Back

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

Front

What does the y-axis represent on a graph?

Back

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

Front

What is the origin in a coordinate plane?

Back

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

Front

How do you find the distance between two points on a graph?

Back

Use the distance formula: Distance = √((x2 - x1)² + (y2 - y1)²).

Front

What happens to a point when it is reflected across the y-axis?

Back

The x-coordinate of the point changes sign, while the y-coordinate remains the same.

Front

What is the distance between the points (4, 2) and (4, -8)?

Back

The distance is 10 units.

Front

What is the distance between the points (0, 5) and (0, -5)?

Back

The distance is 10 units.

Front

What is a quadrant in a coordinate plane?

Back

A quadrant is one of the four sections of the coordinate plane, divided by the x-axis and y-axis.

Front

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

Back

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