Evaluate when x= -3 and y= -1: x- xy. Answers A.-4 B.-3 C.0 D.-6

Since you know:

x = -3

y = -1        You can substitute/plug in the values into the equation

x - xy        Plug in -3 for "x", and -1 for "y"

(-3) - (-3)(-1)   Multiply -3 and -1 together  [two negative signs cancel each other out and become positive]
