To find the value of the function $ y = 18x - 13 $ when $ x = -4 $, we can substitute $-4$ for $ x $: $$ y = 18(-4) - 13 $$ $$ y = -72 - 13 $$ $$ y = -85 $$ None of the provided responses match $-85$, so please double-check the given options. If there's an error in the function or values provided, let me know!
