Front

What is the equation of a line?

Back

An equation that describes a straight line in a coordinate plane, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a function?

Back

A relation where each input (x-value) has exactly one output (y-value).

Front

What is a compound inequality?

Back

An inequality that combines two or more inequalities, often using 'and' or 'or'.

Front

What is surface area?

Back

The total area of the surface of a three-dimensional object.

Front

What does 'infinitely many solutions' mean?

Back

It means that there are countless solutions to an equation, often occurring when the equation simplifies to a true statement.

Front

How do you find the slope of a line?

Back

The slope (m) is calculated as the change in y divided by the change in x between two points on the line.

Front

What is the formula for the slope of a line?

Back

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

Front

What is the y-intercept?

Back

The point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

What is the difference between 'and' and 'or' in compound inequalities?

Back

'And' means both conditions must be true, while 'or' means at least one condition must be true.

Front

What is the formula for the surface area of a rectangular box?

Back

SA = 2(lw + lh + wh), where l is length, w is width, and h is height.
