Front

What is the definition of a function?

Back

Every input has only ONE output.

Front

Which graph matches the inequality k < 3?

Back

Graph A

Front

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

Back

-1/5

Front

Find the slope of the line that passes through (0, 0) and (2, 5).

Back

5/2

Front

What is the slope-intercept form of a line?

Back

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

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is an inequality?

Back

A mathematical statement that compares two expressions using <, >, ≤, or ≥.

Front

What does it mean for a function to be linear?

Back

It can be represented by a straight line on a graph.
