Question

the cost of a antivirus software package is $65 for the 1st year and $10 for each annual renewal of the independent variable is the number of renewals and the dependent is amount paid, what is the slope and y-intercept of the graph of the equation representing this situation (assume x-axis is labeled as renewed y-axis is labeled as dollars.

Answer 1

Understand the problem carefully which is the only solution you have when you construct equations depicting the relationship between variables. For this problem, the equation would be:

y = 65 + 10x
where x is the number of years
y is the cost

The slope-intercept form equation is y = mx + b, where m is the slope and b is the intercept. Therefore, in this problem, the slope is 10 and the y-intercept is 65.
