What is the value of the function y=1/8x−13 when x=−4?.
To find the value of the function when x = -4, substitute -4 into the equation:
y = 1/8(-4) - 13
Simplifying,
y = -1/2 - 13
y = -1/2 - 26/2
y = -27/2
Therefore, when x = -4, the value of the function y = 1/8x - 13 is -27/2.

I apologize for the error in my response. Let me correct it.
To find the value of the function when x = -4, substitute -4 into the equation:
y = 1/8(-4) - 13
y = -4/8 - 13
y = -1/2 - 13
y = -1/2 - 26/2
y = -27/2
Therefore, when x = -4, the value of the function y = 1/8x - 13 is -27/2.
To find the value of the function y = 1/8x - 13 when x = -4, we can substitute -4 for x in the equation and perform the calculations step by step.
1. Start with the equation: y = 1/8x - 13
2. Substitute x = -4 into the equation: y = 1/8(-4) - 13
3. Simplify the expression: y = (-4/8) - 13
4. Perform the division: y = -1/2 - 13
5. Find a common denominator for the fractions: y = -1/2 - (26/2)
6. Combine the fractions: y = (-1 - 26)/2
7. Simplify further: y = -27/2
Hence, the value of the function y = 1/8x - 13 when x = -4 is -27/2.
