Assessment: 15-Point Assessment #4 (of 4)    due: Wednesday 4/25; Thursday 4/26

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

Problems a-o use the following two linear functions:

      f(x) = 5x - 10            g(x) = 4 - 2(x)

a:  Record the slope of f(x).
b:  Record the vertical-intercept for f(x).
c:  Record the horizontal-intercept for f(x).
d:  Is f(x) an increasing, decreasing, or constant function?
e:  Evaluate:  f(5)
f:  f(x) = 55  when  x  equals what?
g:  Graph f(x).

h:  Record the slope for g(x).
i:  Record the vertical-intercept for g(x).
j:  Record the horizontal-intercept for g(x).
k:  If g(x) an increasing, decreasing, or constant function?
l:  Evaluate:  g(-5)
m:  g(x) = 64  when  x  equals what?
n:  Graph g(x).

o:  Find the slope between the points (2, -5) and (-3, 4).

p:  Find the equation of a line in slope-intercept form having
    a slope of five and a vertical-intercept of (0, 3).

q:  Find the equation of a line in slope-intercept form having
    a slope of negative two that passes through (6, -3).

r:  Find the equation of a line in slope-intercept form that
    passes through the points (-1, 1) and (-4, 4).

s:  No or Yes:  Increasing functions have a negative slope.
t:  No or Yes:  Decreasing functions have a positive slope.
u:  No or Yes:  Constant functions have a slope of zero.
