Key Concept

100

Has a constant rate of change and forms a straight line

What is a Linear Relationship

200

Is linear and it goes through the origin (0,0)

What is a Proportional Relationship

300

Any linear function can be expressed by an equation in the form of ________

What is Y=mx+b

400

The value of "m" also tells the steepness and direction (upward or downward) of the graph of the function

What is a Slope

500

The "b" tells the point at which the graph of the function crosses the y-axis. That point has coordinates (0,b) and is called the ___________

What is a Y-Intercept

How can you determine whether a relationship is linear from a graph, a table or an equation

100

Straight line

What is a Graph

400

This number is also called the ____________

Coefficient in front of the variable x

500

What does the b stand for in the equation and what the terms means

What is the Y-Intercept and it is found on the Y-Axis

Key concept for Section 9

100

What does a non-linear relationship look like from a Table?

It has no constant rate of change in y divided by change in x is not equal

200

What does a non-linear relationship look like from a graph?

Does NOT form a straight line

300

What does a non-linear relationship look like in an equation?

Cannot be written in an mx+b form. The exponent with the variables is not equal to one.
