The answer to the question is 29
9514 1404 393
Answer:
9/8
Step-by-step explanation:
The equation of a proportional relationship is ...
y = kx
The constant of proportionality, k, can be found from ...
k = y/x . . . . . above equation divided by x
Using the given points, we find the constant of proportionality to be ...
k = (3/4)/(2/3) = (3/4)(3/2) = 9/8
The constant of proportionality is 9/8.
<u>Answer:</u>
The correct answer option is D. (-2, 1).
<u>Step-by-step explanation:</u>
We are given the coordinates of the square A"B"C"D" after the rule is applied and we are to find the coordinates of the vertex A.
For that, we will reverse the rule.
A" = (-5, -3)
x: - 5 + 4 = -1
y: - 3 + 1 = -2
Now we will reverse the 90 degrees counter in counter clockwise rotation:
(x, y) ---> (y, -x)
(-1. -2) ---> (-2, -(-1)) = (-2, 1)
y will equal negative 1 cause one half over 2 plus y equals negative 1
