For this problem you need to understand that a linear graph is a straight line (Remember Rise/Run). A continous function is <span>a </span>continuous function<span> is a </span>function <span>for which sufficiently small changes in the input result in arbitrarily small changes in the output, so we can already cross off that as an answer. The Y-Intercept is the cost (in dollars), so this would be to monthly fee. Now, onto the rate of change. T</span>he rate of change is <span>represented by the slope of a line. So the more classes you take the more it will increase. Therefore the cost for one class is the rate of change. Lastly, the cost for one class is $10. It's not, since $10 is the intial fee to belong to a gym, so this is false.
Recap: True -The relationship is linear -The y-intercept represents the monthly fee. -The rate of change represents the cost for one class. False -The relationship represents a continuous function. -The cost for one class is $10. I hope I've helped you, have a great day!</span>
Side note: you can use the nCr formula to compute ; however, it's much quicker to use the shortcut formula . You can also use Pascal's Triangle to find the value of
