IM Mid Unit 7 Review

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

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 as (x, y).

Front

How do you determine the length of a side of a rectangle given its coordinates?

Back

Calculate the distance between two points on the same side using the distance formula.

Front

What does the inequality x ≥ -5 represent on a number line?

Back

It represents all numbers greater than or equal to -5, including -5 itself.

Front

What type of circle is used to represent an inequality that includes the number, such as x ≤ 3?

Back

A closed circle is used to indicate that the number is included.

Front

What is the difference between an open circle and a closed circle on a number line?

Back

An open circle indicates that the number is not included, while a closed circle indicates that it is included.

Front

How do you find the shortest side of a rectangle given its coordinates?

Back

Identify the lengths of the sides using the distance formula and choose the smallest length.

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

If a point is located at (2, 0), what does this indicate about its position?

Back

It is 2 units to the right of the origin and 0 units up or down.
