What is the value of the function y =1/8x-13 when x =-4

0 -12.5
0 -16
0 -13.5
0-15
x - 13 when x = -4? (1 point)

When x = -4, the value of the function y = 1/8x - 13 is:

y = 1/8(-4) - 13
y = -1/2 - 13
y = -13.5

Therefore, the value of the function is -13.5 when x = -4.

Therefore, the correct answer is "0 -13.5".
