the equation of a line perpendicular to
and passes through the point (-6,8) is 
Step-by-step explanation:
We need to write equation of line perpendicular to
and passes through the point (-6,8)
Since the line
is in slope-inetercept form 
the slope of line m = 0.25
As, the new line is perpendicular to the given line so, slopes of lines that are perpendicular are: slope = -1/slope1
So, slope will be -1/0.25 = -4
Now, finding y-intercept.

So, value of y-intercept b = 30
Now the equation of the required line having slope m= -4 and b =30 will be:

So, the equation of a line perpendicular to
and passes through the point (-6,8) is

Answer:
Cost of per session the average rate is $45.
Step-by-step explanation:
It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.
It is required to find what is the cost per session.
Step 1 of 1
It is given that a gym membership with two personal training session cost $125, while gym membership with five personal training sessions cost $260.
To find the cost of per session calculate the average rate.
Now let $f(x)$ be the cost per session use the for the average rate of change, and the input value is the number of personal traings x.

Now substitute, $125 for
, 260 for
for
and 5 for
then,

Cost of per session the average rate is $45.
The fraction would be the portion over the total:
240 / 5280
Divide both top and bottom by 240 and the fraction simplifies to 1/22
The answer is 1/22
