I believe it could be the third answer.
Answer:
A. (3 , 1)
Step-by-step explanation:
Note the placement of x and y for points:
(x , y)
Plug in the corresponding numbers for the corresponding variables:
(x , y) = (3 , 1)
y = x - 2
(1) = (3) - 2
1 = 3 - 2
1 = 1 (True).
A. (3 , 1) is your answer.

Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
