Use the slope equation: \frac{y2-y1}{x2-x1}

Plug in the points (2, 15) and (0, -1).
\frac{-1-15}{0-2} ⇒ \frac{-16}{-2} = 8

The slope of the line is 8.

leva [86]

Answer:

t α 1 /r ; t = k/r

Step-by-step explanation:

Given that :

Time taken, t varies inverse as rate, r

MATHEMATICALLY,

t α 1 /r

Hence,

t = k/r ;

Where, k is the proportionality constant

Hence, the situation could be expressed as :

t = k/r OR

t α 1 /r
