Bill casler bought a $1000, 9-month certificate of deposit (cd) that would earn 8% annual simple interest. three months before the cd was due to mature, bill needed his cd money, so a friend agreed to lend him money and receive the value of the cd when it matured.

value = ? $
(b) if their agreement allowed the friend to earn a 10% annual simple interest return on his loan to bill, how much did bill receive from his friend? (round your answer to the nearest cent.) value = ?
3x - 2y = 31
the 2-point form of the equation for a line is useful for this. for points (x1, y1) and (x2, y2), it tells you
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
substituting the given point values, we get
y = (4 ))/(13 -5)·(x -5) +(-8)
y = (12/8)(x -5) - 8 = (3/2)(x -5) -8
multiplying by 2 gives
2y = 3(x -5) -16
2y = 3x -15 -16
adding 31-2y changes this to standard form:
3x -2y = 31
