Input (x-value)
Output (y-value)
You need to find the x-value that produces a y-value of -1. Since you know:
y = -1       Use the rule, and substitute/plug this into the equation
y = -2x + 33       Plug in -1 for "y" in the equation since y = -1
-1 = -2x + 33        Subtract 33 on both sides
-1 - 33 = -2x + 33 - 33
-34 = -2x      Divide -2 on both sides to get "x" by itself

17 = x
An input of 17 yields an output of -1

The choose C. –2/15
 (-2/15) +(-13/5) =(-13/5) +a/b
a/b = (-2/15)+(-13/5) - (-13/5)
a/b = (-2/15) - ( 39/15) +(39/15)
a/b = –2/15
