Y - y1 = m (x + x1)

Solve for m by subtracting the y's and dividing them by the difference of the 2 x's.

-32 - 1 = -33
-8 - 3 = -11

Divide the two to get 3.

Use the first point (as instructed) and plug it into the equation.

y - (-32) = 3 (x - (-8))

y + [32] = [3] (x + [5])

The brackets are the fill in the blanks.

Answer:  5 cos x

<u>Step-by-step explanation:</u>

y = sin x     is       y = cos x        shifted to the right π/2 units.

y = 5 sin (x + π/2)     is a shift to the left π/2 units (which results in cos x) and    .                                 an amplitude of 5.

--> y = 5 cos x

David lives 3 2/3 miles from the lake. Mariel lives2 1/2 times as far from the lake as David does.
jek_recluse [69]
(3 + (2/3))(2+(1/2) = 3*2+2*(2/3)+3*(1/2)+((2/3)(1/2)) = 6+(4/3) +(3/2) + (2/6) = 6 + ((8+9+2)/6) = 6 + (19/6) = 6 + 3 + 1/6 = 9 + 1/6 miles = D
