7.RP.2.A

Which of the following pairs of ratios are equivalent?

• Yes, because the graph is a curve.

• No, because the graph is a straight line.

Which graph represents a proportional relationship?

• A straight line that passes through the point (0, 1).

• A straight line that passes through the origin (0, 0).

• A curved line that passes through the origin (0, 0).

• A horizontal line.

• Yes, because the graph is a curve.

• No, because the graph is a straight line.

• 8:10

• 5:4

• 12:15

• 10:8

A graph shows a line passing through the points (0, 0) and (3, 6). Is this a proportional relationship?

• Yes, because the line passes through the origin.

• No, because the line does not pass through the origin.

• Yes, because the line is horizontal.

• No, because the line is vertical.

• Yes, because the graph is a curve.

• No, because the graph is a straight line.

Which of the following graphs does not represent a proportional relationship?

• A straight line through the origin.

• A straight line through (0, 2).

• A straight line through the origin with a positive slope.

• A straight line through the origin with a negative slope.

Which equation does not represent a proportional relationship?

• Yes, because the graph is a curve.

• No, because the graph is a straight line.
