1.    Which point is in Quadrant III ?
(-4, -5)
( 3, 2)
( 2, -3)
(-6, 7)
2.   Which equation would you use to model the
height of an object that is thrown down with an
initial velocity of -10 feet per second from a height
of 300ft ?
h = -16t2 - 10t - 300
h =-16t2 + 300
h = -16t2 + 10t - 300
h = -16t2 - 10t +300

8.   At a coffe shop I paid $16.50 for 4 lattes and
 2 scones.  Another customer paid $15.50 for 3 lattes
 and 4 scones.  Which system of equations can be
used to determine cost x of one latte and cost y of
one scone?
4x + 2y = 16.50
     3x + 4y = 15.50
y = 4x - 16.50
     y = 3x - 15.50
x + y = 16.50
     x  + y = 15.50
4x + 3y = 16.50
    2x + 4y = 15.50
