Front

Identify the error in Austin's work: He combined -3 and -9 incorrectly.

Back

Austin did not combine -3 and -9 correctly.

Front

What is the constant of proportionality (slope) if the answer is $9?

Back

$9

Front

Define 'inequality' in mathematics.

Back

An inequality is a mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.

Front

What does 'slope' represent in a graph?

Back

The slope represents the rate of change of a line, indicating how steep it is.

Front

Explain the term 'constant of proportionality'.

Back

The constant of proportionality is the constant ratio between two variables that are directly proportional.

Front

What is the formula for calculating slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points.

Front

What does it mean to 'combine like terms' in an equation?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.
