$x ∣ y$ $"   "x | "  "y$
$——----$ $"——––––"$
$–5 | "   "47$
$–1 | "     "7$
$"   "0 | "  "–3$
$"   "1 | –13$

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.
