Answer:

The slope or incline is -5

Step-by-step explanation:

rewrite to get the form

y = ...

x - 5y = -10

- 5y = -10 -x

divide left and right if the = sign by -5 gives:

(-5/-5)y = (-1/-5)x + (-10/-5)

y = 1/5x +2

So the incline is 1/5

a perpendicular line has an incline of -1 *5/1 = -5

The slope or incline is -5

Answer:

a = 36

Step-by-step explanation:

A stationary point is where the function derivative is zero. Here, we have ...

y' = 2kx -16/x^2 = 0

For x = 2/3, this is ...

4/3k -16/(4/9) = 0

4/3k = 36

k = 27

Then the value of y at that point is ...

y = 27(2/3)^2 + 16/(2/3) = 12 +24 = 36

The stationary point of interest is (2/3, a) = (2/3, 36). a = 36.
