You can immediately eliminate options C and D because they don’t have y cubed. And you can eliminate A because it’s subtracting y cubed for half of at so that only leaves answer B as the answer.
Since you haven't added a diagram of the triangle, I'll just tell you how to identify the sides.
The side opposite to the right angle is the "opposite" side while the side adjacent to the right angle is the "adjacent" side. The hypotenuse of the right-angles triangle is the side opposite to the right angle.
As an example, please take a look at the attached image:
Taking a look at this image, we will find that:
both a and b are adjacent sides while c is the opposite of the right angle. c is also considered as the hypotenuse of the triangle.
The gradient of this line is 9 so the gradient of the perpendicular line is -1/9 (the two perpendicular gradients must multiply to get -1).
The equation of a line is y=mx+c
where m is the gradient and c is the y intercept
We can then just substitute values in:
y = -1/9(x) -2
Answer:
X= -19
