Answer 1

To find the value of the function \( y = 18x - 13 \) when \( x = -4 \), substitute \(-4\) for \(x\):

\[
y = 18(-4) - 13
\]

Calculating:

\[
y = -72 - 13
\]
\[
y = -85
\]

It seems that none of the provided responses match the calculated value of \(-85\). Please check the problem or the response options again!
