What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the equation of a line (y = mx + b). It is calculated as the rise over run, or the change in y divided by the change in x.

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

Can the sides 1, 1, 2 form a triangle?

Back

No, because the sum of the lengths of the two shorter sides (1 + 1 = 2) is not greater than the length of the longest side (2).

What are the angle measures in a triangle?

Back

The sum of the interior angles in a triangle is always 180 degrees.

Write an equation for the total cost of items purchased: You bought a $5 magazine and four erasers for a total of $25.

Back

5 + 4x = 25, where x is the cost of each eraser.

Front

What does it mean for angles to be complementary?

Back

Two angles are complementary if the sum of their measures is 90 degrees.

Front

What does it mean for angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b.

Front

What is the formula for calculating the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 * base * height.

What is a variable in mathematics?

Back

A variable is a symbol, often represented by letters, that stands for a number that can change or vary.
