Sometimes is the answer. The altitude of a triangle is a perpendicular bisector when the triangle is isosceles.

The monthly cost of cell phone is A = 40 + 0.005 m</h3>
Step-by-step explanation:
The monthly fixed charges by mobile company = $40
The cost of sending each text message = 0.05 cents
Now, 100 cents = 1 dollar
⇒ 1 cent =$ 
⇒ 0.05 cent s =$ 
Also, the number of text messages send = m
So, the cost of sending m text message = m x ( cost of 1 text )
= m x ( $ 0.0005) = 0.0005 m
Now, Total bill = Fixed rate + cost of m texts
⇒ A =$40 + $ 0.0005 m
Hence, the monthly cost of cell phone is A = 40 + 0.005 m

Explanation:
The function is 
To graph the function, let us find the x and y intercepts.
To find x-intercept, let us substitute y=0 in the function 

Thus, the x-intercept is 
To find the y-intercept, let us substitute x=0, we get,

Thus, the y-intercept is 
The graph has no asymptotes.
To plot the points in the graph, we need to substitute the values for x in the function
, to find the y-values.
The points are
. The image of the graph and table is attached below:
