• y = x + 6

• y = 6x - 1

• y = -x + 6

• y = 4x + 6

Does this graph represent a proportional relationship? Why?

• No, because it doesn't pass through the origin.

• Yes, because it doesn't pass through the origin.

• Yes, because it intersects the y axis.

• No, because it intersects the x axis.

Valley Video charges a $15 annual fee plus $3 per movie for rentals. Last year, Jennifer spent $99 at the video store. How many movies did she rent? Write the linear equation and solve for the number of movies.

• 15x + 3x = 99    and 6 movies
• 15x + 3 = 99 and 6 movies
• 3x + 15 = 99 and 28 movies
• 3x + 99 = 15 and 28 movies
