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.

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

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.

e) none of the above because the measure of angle cba is 101°
