Answer:

Instantaneous slope  is \frac{1}{5}

Step-by-step explanation:

the instantaneous slope of y=-5\x at x=5

y=\frac{-5}{x}

To find instantaneous slope we take derivative of y

Derivative of 1/x is -1/x^2

y'=\frac{5}{x^2}

We need to find out instantaneous slope at x=5

so we plug in 5 for x in y'

y'=\frac{5}{x^2}

y'=\frac{5}{5^2}

y'=\frac{5}{25}

y'=\frac{1}{5}

Instantaneous slope  is \frac{1}{5}
