#"   "x | "  "y#
#"——––––"#
#–5 | "   "47#
#–1 | "     "7#
#"   "0 | "  "–3#
#"   "1 | –13#

For each value of #x# given in the table, we plug it into the equation #y=–10x-3# to get the matching value for #y.#

When #x=–5:#

#y=–10(–5)-3#
#color(white)y=" "50" "-3#
#color(white)y=47#

So when #x = –5#, we have #y=47#. The first row of our table should be #–5 | 47.#

Similarly, when #x = –1#:

#y=–10(–1)-3#
#color(white)y=" "10" "-3#
#color(white)y=7#

So when #x = –1,# we have #y = 7.# The second row of our table should be #–1 | 7.#

I'll leave the rest of the #y#'s as an exercise for you.
