I forgot about how you do this and answer. Do you mind to also explain the steps?

C.

Step-by-step explanation:

First, call the unknown angle x.

Use the Exterior Angle Theorem:

140 = 45 + x

x = 95°

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

step-by-step explanation:

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
