What is the absolute value of a number?

Back

The absolute value of a number is its distance from zero on the number line, regardless of direction. For example, |-5| = 5 and |5| = 5.

Front

How do you compare two absolute values using >, <, or =?

Back

To compare two absolute values, calculate each absolute value and then compare the results. For example, |-23| < |-28| because 23 < 28.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is given by the formula: Area = (base * height) / 2.

Front

Calculate the area of a triangle with base 5 units and height 8 units.

Back

Area = (5 * 8) / 2 = 20 square units.

Front

What is the x-axis?

Back

The x-axis is the horizontal axis in a coordinate plane, where the y-coordinate is zero.

Front

What is the y-axis?

Back

The y-axis is the vertical axis in a coordinate plane, where the x-coordinate is zero.

Front

How do you find the coordinates of a point on the y-axis?

Back

A point on the y-axis has coordinates of the form (0, y), where y can be any real number.

Front

What does it mean for two numbers to be equal?

Back

Two numbers are equal if they represent the same value. For example, 3 = 3.

Front

What is the relationship between negative numbers and their absolute values?

Back

The absolute value of a negative number is the positive version of that number. For example, |-22| = 22.

Front

How do you determine if one absolute value is greater than another?

Back

Compare the two absolute values directly. For example, |-13| > |11| because 13 > 11.
