Answer:

<h3>The slope  = - 7/4</h3>

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (9, 1) and (5, 8). Substitute:

m=\dfrac{8-1}{5-9}=\dfrac{7}{-4}=-\dfrac{7}{4}

Answer:

log_{2}( \frac{1}{8} )  =  - 3

Step-by-step explanation:

Think of Log as a complimentary operation to powers.

log_{2}( \frac{1}{8} )

means you need to find the exponent of 2 that yields 1/8.

As this number is putting the base on the denominator, we know for a fact it must be some negative number, or

{2}^{ - x}  =  \frac{1}{ {2}^{x} }

Then, by trial and error works just fine, going through the powers of 2.

{2}^{-2} = \frac{1}{ {2}^{2} }  =  \frac{1}{4}  \\ {2}^{-3} = \frac{1}{{2}^{3} }  =  \frac{1}{8}

And that is it.

Answer:

y = 25x - 85

Step-by-step explanation:

Every second (x) that passes by is 25 meters gained, and since she's 85 meters away from the safe distance still, the y intercept is -85.
