Answer:

The answer is 1/9.

Step-by-step explanation:

When solving for the slope of a perpendicular line to a given, you have to flip the opposite reciprocal.

First take the number and flip the reciprocal, in this case -9 turns into -1/9.

Then flip the sign, like making a negative to a positive or a positive to a negative. In this case make -1/9 into 1/9

Therefore the answer is 1/9.

The profit earned by a hot dog stand is a linear function of the number of hot dogs sold. It costs the owner $48 dollars each mo

Natasha2012 [34]

Answer:

$y=2x-48$

Step-by-step explanation:

Let

y -----> the profit earned by the hot dog stand daily

x ----> the number of hot dogs sold

we know that

The linear equation that represent this problem is equal to

$y=2x-48$

This is the equation of the line into slope intercept form

where

$m=2\frac{\$}{hot\ dog}$ ----> is the slope

$b=-\$48$ ---> is the y-intercept (cost of the day's supply)
