Answer:

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : x1 = 3 and y1 =2

let A(3,2) B(-9,6)

the slope is : m = (YB - YA)/(XB -XA)

(6-2)/(-9-3) =4/(-12) = -1/3

the slope is m = -1/3

The equation is : y – y1 = m(x – x1)

y-2 =-1/3 ( x-3)

or : 3y-6 = -x+3

At noon, ship a is 40 nautical miles due west of ship b. ship a is sailing west at 18 knots and ship b is sailing north at 17 kn

igor_vitrenko [27]

The distance between the ships changing at 92.29 Knots

Using the position of ship A as the reference point, at time t measured in hours past noon, ship A is 18 t miles west of this point and ship B is 40 + 17t north of this point.
The distance between ships is then

$d(t) = \sqrt{(18t)^{2} + (40+17t)^{2} } \\$
