Do not lose this assessment. Do all your math on your own paper. Do not write on this assessment.

a.  Determine the slope of the line passing through (4, -2) and (-3, -5).
b.  Choose the ordered-pair which is a solution of the 
    linear equation:   y - 5 = 4(x + 2)

    A)  (-3, 1)   B) (1, -3)   C)  (-4, -3)   D)  (-3, -4)

c.  Write the equation  5x - y = 25  in slope-intercept form.
d.  Write the equation of a horizontal line that passes through (-3, 5).
e.  Find the slope:  x = -3
f.  Find the vertical-intercept:  2x - 4y = 8
g.  The slope of a decreasing function is always what?
h.  Find the vertical-intercept:  y = -7x
i.  Find the slope:  y = 91 - x 
j.  Find the slope:  y - 3 = 2(x + 4)
k.  Find the slope for the following ordered-pairs.
    (10, 6)  (8, 3)  (6, 0)  (4, -3)  (2, -6)  (0, -9)  (-2, -12)

l.  C(n) = 86(n) + 15  calculates the tuition cost to take  n  credits 
    at SCC.  How many credits can be taken given $789?

m.  Solve the following system of linear equations:
          2x - 4y = 5  ...and...  6x + 4y = 11

n.  T(y) represents the tuition (in dollars) at SCC and 'y' is the school 
    year with y = 0 representing the year 1970.  Interpret (briefly 
    explain) the equation:  T(44) = 81

o.  Record the point that the line  y - 3 = 4(x + 2)  passes through. 

p.  The following table represents the yearly sales for Widgets Inc.

       t (years since 2001):         2    5    7   12   16
       ---------------------------------------------------
       S(t) (sales in $ millions):   3    8   12    5   14

    Briefly explain the meaning of  S(5).

q.  Zelmo pays off his debt at a constant rate of $50 per month.
    The balance of his debt is $2,000. How much debt will remain
    after six months?

r.  Graph a linear function with a slope of -(4/7) that pass through
    the point (3, -5). The intercepts must also be graphed.
