The equation for the problem is y = 4x + 40. The slope is 4 and the y intercept is 40
The standard equation for a linear equation is given by:
y = mx + b
Where m is the slope of the equation, b is the y intercept, y is a dependent variable and x is the independent variable.
Let x represent the charge per megabyte used and let y represent the total charge for the month
since there is a $40 monthly fee and you are charged $4 per megabyte of data used, hence:
y = 4x + 40
Comparing with the standard linear equation:
The y intercept is 40, this means that even if no data is used, $40 must be paid.
The slope is 4, that is for every megabyte used, $4 is paid.
The amount to pay for 10 MB is:
y = 4(10) + 40 = $80
$80 is paid to use 10 megabytes
