Directions. Identify the constant of proportionality for the following questions. Be sure to show your work or explain how you got your answer.#1) x=4 and y=1.#2) 108/36=3 so x=3 and y=1.#3) 80 dollars earned in 5 hours divided is 16 so 16 dollars an hour.#4) $200/4 gift cards is $50 for 1 card.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
