5. Find the slope of the line that goes through (-1, 3) and (3, 7).

6. Find the equation of the line that goes through the point (4, 3) with a slope of 3/2.

7. Suppose that you
open a bank account and after 3 months you have $200 in the account, and after 7 months you have $400. Let *x* denote the number of months and *y* denote the amount of money you have in the bank. Find a linear equation which will give you these amounts of money at these times. Use that equation to
predict how much money you would have in the bank after 12 months if the balance continued to grow linearly at this rate.
