Question
Can someone help me with this?
The equation given is:

\[ x = 8 + 3t, \quad y = -8t \]

You are asked to find the derivative:

\[ \frac{dy}{dx} = \]

To solve for \(\frac{dy}{dx}\):

1. Find \(\frac{dx}{dt} = 3\).
2. Find \(\frac{dy}{dt} = -8\).

Use the chain rule to find \(\frac{dy}{dx}\):

\[
\frac{dy}{dx} = \frac{dy}{dt} \div \frac{dx}{dt} = \frac{-8}{3}
\]

Therefore, \(\frac{dy}{dx} = \frac{-8}{3}\).
