Front

What is the slope of a line?

Back

The slope is the ratio of the rise (change in y) to the run (change in x).

Front

What is the equation of a line in slope-intercept form?

Back

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

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are negative reciprocals of each other.

Front

How do you find the domain of a function?

Back

Identify all possible input values (x-values) that do not cause division by zero or take square roots of negative numbers.

Front

What is a quadratic function?

Back
