Given :
Service cost , c = $40.
Amount paid for each message , m = $0.02 .
To Find :
Equation represents the total cost C in dollars for a month when eric send t text message.
Solution :
Let , total cost be C .
It is an linear equation with slope equal to 0.02 and y-intercept equal to 40.
So ,
Hence, this is the required solution.
Answer:
Step-by-step explanation:
The slope of a line perpendicular to another line is the opposite reciprocal of the slope of the other line, meaning if the slope of the other line is , then the slope of the line perpendicular is
.
Knowing this, we can start to construct the equation for the line:
To solve for , we plug in the coordinates of the point that we know the line runs through,
:
Therefore, the slope of the line that is perpendicular ot the line provided in the equation is the following:
