The terminal side of θ passes through the point (7, −1) .

What is the exact value of sinθ in simplified form?

If I understand the question properly, none of those are the answer

The point is in the forth quad so sin is negative

opposite is 1

$$hypotenuse\;\; is\;\; \sqrt{50}=5\sqrt2\\ sin \theta = \frac{-1}{5\sqrt2} = \frac{-\sqrt2 }{ 10}$$
