Question

Y=-10X-3 fill in the table?

X y
-5 ?
-1 ?
0 ?
1 ?

Answer 1

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

Explanation:

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.
