Pre-Algebra Assessment

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 is the opposite of a number?

Back

The opposite of a number is the number that is the same distance from zero on the number line but in the opposite direction.

Front

What symbols are used for closed dots when graphing inequalities?

Back

Closed dots are used for the symbols ≤ (less than or equal to) and ≥ (greater than or equal to).

Front

How do you calculate the depth below sea level?

Back

To calculate depth below sea level, subtract the distance swum up from the total depth.

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

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).

Front

What does it mean to graph an inequality?

Back

Graphing an inequality involves representing the solutions of the inequality on a number line or coordinate plane.

Front

What is the difference between a closed dot and an open dot on a graph?

Back

A closed dot indicates that the number is included in the solution (≤ or ≥), while an open dot indicates that the number is not included (< or >).

Front

How do you find the area of a quadrilateral?

Back

To find the area of a quadrilateral, you can divide it into triangles or rectangles and sum their areas.

Front

What is the x-coordinate in an ordered pair?

Back

The x-coordinate is the first number in an ordered pair, representing the horizontal position on the coordinate plane.
