Answer:
It is B. hyperbola, 45 degrees.
SteIt is p-by-step explanation:
If we rotate the standard form x^2 - y^2 = 1 through 45 degrees we get xy = 1/2.
xy = -2.5 comes from x^2 - y^2 = -5 being rotated 45 degrees.
You have to divide both sides by 5 because it states"5t" and you should get "t=20"
Substitute the values into the equation
2(2)+4(-1)-5(1)
4-4-5
-5
