Kay drew a parallelogram on her paper. She then tore the parallelogram into two pieces together as shown. What statement did Kay's experiment support? pl help me

the answer is (-4,-4)

hope this ! : d

i think it would be 42cm

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
