Define unit rate.

• A unit rate is a rate in which the second term is 1 unit.

• A unit rate is a rate in which the second term is 0 unit.

• A unit rate is a rate in which both terms are 1 unit.

• A unit rate is a rate in which the first term is 1 unit.

How do you graph proportional relationships?

• Connect the points with a curved line on a coordinate plane.

• Plot the points on a coordinate plane and connect them with a straight line.

• Plot the points on a scatter plot.

• Use a bar graph to represent the data.

What are the characteristics of proportional relationships?

• The characteristics of proportional relationships are a constant ratio, direct proportion, and a straight line graph passing through the origin.

• The characteristics of proportional relationships are a variable ratio, inverse proportion, and a curved line graph.

• The characteristics of proportional relationships are a changing ratio, indirect proportion, and a horizontal line graph.

• The characteristics of proportional relationships are a fixed ratio, inverse proportion, and a vertical line graph.

Identify whether the following relationship is proportional: y = 2x

• No

• Sometimes

• Not enough information provided

• Yes

A proportional relationship can be written as an equation in the form:

• y = k+x
• y = k-x
• y = kx
• y = k/x

Is the graph proportional?

• Yes

• No, it does not go through the origin

• Not enough information

• No, it is not straight
