5) Find the slope of the line through the points (5, -7) and (-2, 6).
6) Write in point-slope form, y  y1  m  x  x1  , the equation of the line through the two points
given in #5.
7) Convert the equation that you wrote in #6 to slope-intercept form, y  mx  b .
8) Convert the equation that you wrote in #6 to standard form, Ax  By  C , where A, B, and C
are integers and A > 0.
9) Given a line with equation -5x + y = -6. Write an equation in point-slope form of the line
perpendicular to the given line through the point (-1, 2).
10) The manager at a local Best Buy store kept track of daily sales of the iPhone 6 when it was
first introduced. He noticed that sales were very high at first, but showed a steady decrease. For
example, on day 5 after the phones first went on sale, the store sold 239 iPhone 6’s, but on day
10 after the phones first went on sale, the store sold only 164 iPhone 6’s. Assume that the
relationship between number of days since the phone became available and number sold is linear
and, let x = the number of days since the phone was released and y = number of phones sold at
this Best Buy store.
a) Write two ordered pairs to represent the sales on the days described.
b) Find the slope of the line through those ordered pairs.
c) Write an equation in point-slope form of the line.
d) Convert the equation to slope-intercept form.
e) Explain what the slope and the y-intercept mean in the context of this problem.
