You sign up for an unlimited text messaging plan for your cell phone. The equation y = 20 represents the cost y (in dollars) for sending x text messages. Graph the equation. What does the graph tell you.

Respuesta :

shiehk
the first point would be
(0,20)
so then 
(1, 40)
(2,60)
this tells you that  the more text messages the more the whole cost will be
sorry if this is not helpful at all

Answer:

The graph of equation is a horizontal line which passes through the point (0,20). It represents the the cost of for sending infinite messages is $20.

Step-by-step explanation:

The given equation is

[tex]y=20[/tex]

where, y represents the cost for sending x text messages in dollars.

The given equation represents a constant function because it is free from x.

The table of values is shown below.

x         y

0         20

1         20

2         20  

Plot these ordered pairs on a coordinate plane and then connect them by a straight line.

The graph is defined for non negative values of x.

The graph of equation is a horizontal line which passes through the point (0,20). It represents the the cost of for sending infinite messages is $20.
