Hey free points ! people i have a few math questions on my profile consider looking at them i have to get done in 30 mins!

You just purchased two coins at a price of $670 each. because one of the coins is more collectible, you believe that its value will increase at a rate of 7.1 percent per year, while you believe the second coin will only increase at 6.5 percent per year. if you are correct, how much more will the first coin be worth in 15 years?

The points (1, 7) and (0, 2) fall on a particular line. what is its equation in slope-intercept form?
