What is an ordered pair in a coordinate system?

Back

An ordered pair is a pair of numbers used to represent a point in a two-dimensional space, written as (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

Front

What are the coordinates for point D if it is located at (0, -5)?

Back

The coordinates for point D are (0, -5).

Front

How do you find the slope of a line given two points?

Back

The slope (m) is calculated using the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Front

What is the slope of the line that passes through the points (5, 0) and (0, 5)?

Back

The slope of the line is -1.

Front

What is the slope of the line that passes through the points (-6, 4) and (2, 6)?

Back

The slope of the line is 1/4.

Front

What does it mean if the slope of a line is undefined?

Back

An undefined slope indicates a vertical line, where the x-coordinates are the same, resulting in division by zero in the slope formula.

Front

What are the coordinates for point H if it is located at (1, 2)?

Back

The coordinates for point H are (1, 2).

Front

What is the significance of the x-coordinate in an ordered pair?

Back

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

Front

What is the significance of the y-coordinate in an ordered pair?

Back

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

Front

How can you determine if two points lie on a vertical line?

Back

Two points lie on a vertical line if they have the same x-coordinate.
