Question

The art teacher would like all the students to use the same shade of orange. She gives the students a graph to use to determine how much yellow and red paint to use.

Which statement is true?

A)The relationship between red dye and yellow dye is proportional because it has a constant rate of change.
B)The relationship between red dye and yellow dye is non-proportional because the y-intercept of the graph is not at the origin.
C)The relationship between red dye and yellow dye is proportional because the graph is a straight line.
D)The relationship between red dye and yellow dye is non-proportional because the rate of change is positive.The relationship between red dye and yellow dye is non-proportional because the rate of change is positive.

Answer 1

B)

Cz
non proportional because the y-intercept of the graph is not at the origin

Answer 2

B

Explanation:

The correct statement is:

B) The relationship between red dye and yellow dye is non-proportional because the y-intercept of the graph is not at the origin.

In a proportional relationship, the graph should pass through the origin (0,0), indicating that when you have none of one component, you also have none of the other. In this case, the fact that it does not pass through the origin indicates a non-proportional relationship.
