Michael wants to compare the speed of two cars. What is a unit rate in this context?

• A unit rate is a ratio that compares two different quantities with no units of measure.

• A unit rate is a ratio that compares two different quantities with different units of measure, such as miles per hour.

• A unit rate is a ratio that compares two similar quantities with different units of measure.

• A unit rate is a ratio that compares two different quantities with the same units of measure.

Noah is helping his younger brother, Henry, to understand the concept of proportional relationships. He uses the example of earning money by doing chores, where the amount of money earned (y) is directly proportional to the number of chores completed (x). The relationship can be represented by the equation y = 2x. How can they graph this relationship?

• The graph of the proportional relationship y = 2x is a vertical line.

• The graph of the proportional relationship y = 2x is a horizontal line.

• The graph of the proportional relationship y = 2x is a curved line.

• The graph of the proportional relationship y = 2x is a straight line that passes through the origin (0,0) and has a slope of 2.
