To find the value of the function y = 1/8x - 13 when x = -4, plug in x = -4 into the equation and solve for y:

y = 1/8*(-4) - 13

First, calculate the multiplication:
y = -1/2 - 13

Next, since -1/2 is the same as -0.5 when expressed as a decimal:
y = -0.5 - 13

Now, subtract 13 from -0.5:
y = -13.5

So the value of the function y when x = -4 is -13.5.

The correct answer is:

C. -13.5
