How do you find the y-coordinate of the solution to a system of equations?

Back

To find the y-coordinate, solve the system using substitution or elimination methods to find the values of x and y.

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you write a system of equations from a word problem?

Back

Identify the variables, translate the relationships into equations, and ensure the equations represent the conditions given in the problem.

What is the slope-intercept form of a line?

Back

Front

What does it mean for a line to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

What does it mean for a line to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1, meaning they intersect at a right angle.
