Jordan has a jar of quarters. when he has 60 quarters in the jar, the jar weighs 52 ounces. when get is 125 quarters the jar, there jar weighs 65 ounces. what is the weigh of the empty jar?

Think of 2 points:  (60, 52) and (125, 65).
                                                                     65-52             13         1
The slope of the line thru these pts is   m = = = ---
                                                                      125-60           65         5

Then the equation of the line is found from   y = mx + b, which here is
                                                                     125=(1/5)(65) + b

Then 125 - 13 = b, or 112 = b

The equation of this line is then y = 5(x)  + 112.

Notice that when x =, the jar is empty.  It weighs 112 oz.

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
