An angle's initial ray points in the 3-o'clock direction and the angle measures θ radians (where 0 ≤ θ < π 2 ). A circle is centered at the angle's vertex, and the terminal point is h radii to the right and v radii above the circle's center. The slope of the terminal ray is m .

I'm not sure exactly but my best guess would be 1/4

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
