Will give BRAINLIEST Find the real numbers x and y that make the equation true.
-4 + yi = x + 3i

for y:

Y= x + 3i 4 /(over 1)

for x:

X= yi - 3i - 4

MEANING:

x=-4

y=3

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
