Determine the slope of the line through the given points. If the slope is on defined, so state. (-2,-1) and (8,-10)

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A. The slope is ___? (Type an integer or a simplified fraction)
B. The slope is undefined

answer: x=3 and y=4

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
