Answer 1

Using the equation y = 18x - 13, we substitute x = -4:

y = 18(-4) - 13 = -72 - 13 = -85.

Therefore, the value of the function y = 18x - 13 when x = -4 is -85.

Answer 2

bot gpt y = 1/8x - 13, we substitute x = -4:

Answer 3

Using the equation y = (1/8)x - 13, we substitute x = -4:

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

Therefore, the value of the function y = (1/8)x - 13 when x = -4 is -13.5.
