Question

The cost of antivirus software package is $65 for the first year and $10 for each annual renewal. of the independent variable is the number of annual renewals and the dependant variable is the total amount paid, what is the slope and y-intercept of the graph of the equation representing this situation? ( Assume the x axes is labeled as renewals and y axes is labeled as dollars).

A. The slope is 10, the y-intercept is 65
B. The slope is 55. the y-intercept is 10
C. The slope is 10, the y-intercept is 55
D. The slope is 65, the y-intercept is 10

Answer 1

The slope is 65, the y-intercept is10

Answer 2

A. The slope is 10, the y-intercept is 65

Step-by-step explanation:

The equation that represents the cost of the antivirus software package is:

y = 65 + 10*x

where y is the cost (in $), x is the number of renewals, 65 is the y-intercept and 10 is the slope. This is a consequence that at first year (number of renewals = 0) the cost is $65 and after each renewal, $10 are added.
