slope = (y2-y1)/(x2-x1)

1/4 = (y--1)/(6-10)

1/4 = (y+1)/(-4)

multiply by -4 on each side

-1 = y+1

subtract 1 from each side

-2 = y

Answer:

11C4 × 11C5

$\binom{11}{4} \times \binom{11}{5} = \frac{11 \times 10 \times 9 \times 8}{4 \times 3 \times 2 \times 1} \times \frac{11 \times 10 \times 9 \times 8 \times 7}{5 \times 4 \times 3 \times 2 \times 1} = 330 \times 462 = 152460$

If f(x) is an antiderivative of g(x), and g(x) is an antiderivative of h(x), then

Goryan [66]

If f(x) is an anti-derivative of g(x), then g(x) is the derivative of f(x). Similarly, if g(x) is the anti-derivative of h(x), then h(x) must be the derivative of g(x). Therefore, h(x) must be the second derivative of f(x); this is the same as choice A.
