Front

What is the Range of the function if the output is limited to values less than or equal to 6?

Back

y \le 6

Front

Evaluate r(3) if r(x) = 4x + 4. What is r(3)?

Back

r(3) = 16

Front

Find the slope of the line that passes through the points (10, 1) and (5, 2).

Back

Slope = -\frac{1}{5}

Front

Solve the system by elimination: 4x + 9y = 28 and -4x - y = -28. What is the solution?

Back

(7, 0)

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x; it indicates the steepness and direction of the line.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

Slope = \frac{y2 - y1}{x2 - x1}

Front

What is the definition of the range in a function?

Back

The set of all possible output values (y-values) of a function.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has exactly one output.
