Plot the points and then answer the questions: (3, 6) (-2,-4) (1,2)
a. Is this a proportional relationship?
b. What is the constant of proportionality?

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the answer is c.

perimeters = 3√10/5

areas = 90/25

i got it down chief.
