Question

Complete the table for the given rule. Rule: Y = X + 8

X | Y
2. _
0. _
4. _​

Answer 1

Y=x+8

Table

`\boxed{\begin{array}c\bf x&\bf y\\ \rm 2&\rm 10\\ \rm 0&\rm 8\\ \rm 4&\rm 12\end{array}}`

How?

x=2

• y=2+8=10

x=0

• y=0+8=8

x=4

• y=4+8=12

Answer 2

`\large\begin{array}\cline{1-2} x & y \\\cline{1-2} 2 & 10 \\\cline{1-2} 0 & 8 \\\cline{1-2} 4 & 12 \\\cline{1-2}\end{array}`

Explanation:

Given rule:

`y=x+8`

The rule tells us that to the corresponding y-values, simply substitute the given value of x into the given rule:

`x=2 \implies y=2+8=10`

`x=0 \implies y=0+8=8`

`x=4 \implies y=4+8=12`

Therefore, the completed table is:

`\large\begin{array}\cline{1-2} x & y \\\cline{1-2} 2 & 10 \\\cline{1-2} 0 & 8 \\\cline{1-2} 4 & 12 \\\cline{1-2}\end{array}`
