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.
