EDM Unit 4 Review

Front

What is an ordered pair in a coordinate plane?

Back

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

Front

How do you plot the point (6, 7) on a coordinate plane?

Back

Start at the origin (0, 0). Move 6 units to the right on the x-axis, then move 7 units up on the y-axis to plot the point.

Front

What does the first number in an ordered pair represent?

Back

The first number in an ordered pair represents the x-coordinate, which indicates the horizontal position on the coordinate plane.

Front

What does the second number in an ordered pair represent?

Back

The second number in an ordered pair represents the y-coordinate, which indicates the vertical position on the coordinate plane.

Front

What is the value of 23.187 compared to 23.048?

Back

23.187 is greater than 23.048 because it has more tenths.

Front

What does the ordered pair (3, 2) represent in a context of students?

Back

The ordered pair (3, 2) represents a total of 5 students, with 2 of them being girls.

Front

What is the purpose of a coordinate grid?

Back

A coordinate grid is used to visually represent points, lines, and shapes in a two-dimensional space using ordered pairs.

Front

How do you determine which point has the highest value on a coordinate grid?

Back

To determine which point has the highest value, compare the y-coordinates of the points; the point with the highest y-coordinate represents the highest value.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0, 0) on a coordinate plane where the x-axis and y-axis intersect, serving as the reference point for all other points.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis), used to plot points.
