What is the slope of the line represented by the equation 3x + 2y = 16?

Back

The slope is -3/2.

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you solve for m (the slope) in the equation y = mx + b?

Back

m = \frac{y - b}{x}.

What does Q1, Q2, and Q3 represent in a box plot?

Back

Q1 is the first quartile, Q2 is the median, and Q3 is the third quartile.

Front

What is the Interquartile Range (IQR)?

Back

The IQR is the difference between Q3 and Q1.

How do you simplify the polynomial 5x(x - 3) + 2x(x^2 - x) + 5x?

Back

The simplified form is 2x^3 + 3x^2 - 10x.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is less than, greater than, or not equal to the other.

Front

What is a solution to the inequality 2x + 3y < 9?

Back

Front

What is the definition of a polynomial?

Back

A polynomial is an expression consisting of variables raised to whole number powers and coefficients.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression.
