Question

10. Do the ratios -2:1,-4: 2 and - 6:3 represent a proportional relationship? O No, the ratios do not represent a proportional relationship because, when graphed, the line passes through the origin but is not straight. No, the ratios do not represent a proportional relationship because, when graphed, the line is not straight, and it does pass through the origin. Yes, the ratios represent a proportional relationship because, when graphed, the line passes through the origin and is a straight line. No, the ratios do not represent a proportional relationship because, when graphed, the line is straight, but it does not pass through the origin.

Answer 1

For this case we have the following proportions:

-2:1 = -2

-4:2 = -2

-6:3 = -2

If we plot the relationship we got something like this

And then we can conclude that the answer is:

Yes the ratios represent a proportional relationship because when graphed the line passes through the origin and is a straight line
