Answer:

6. A; 7. D

Step-by-step explanation:

6. 2=5j-28 - Add 28 to both sides

30=5j- Divide by 5 to both sides.

6=j

7. 3/5n +3=18- Subtract by 3 on both sides.

3/5n=15- Multiply by the reciprocal of 3/5 to both sides.

The linear function is a function that has a straight line when plotted on a

graph.

<h3>The correct option;</h3>

The table of ordered pairs that represent a linear function is the option; <u>x/y -8/-7 0/0 8/7 16/14</u>

<u />

<h3>Reasons why the above selection is correct:</h3><h3 /><h3>Given;</h3>

The given data can be presented as follows;

x/y -8/22 0/1 8/22 16/102

x/y -8/-7 0/1 8/9 8/2

x/y -8/-7 0/0 8/7 16/14

x/y -8/-7 0/1 8/5 16/4

<h3>Representation of the options in tabular form;</h3>

In a tabular form, we have;

$\begin{tabular}{|c|c|}x&y\\-8&22\\0&1\\8&22\\16&102\end{array}\right]$ $\begin{tabular}{|c|c|}x&y\\-8&-7\\0&1\\8&9\\8&2\end{array}\right]$ $\begin{tabular}{|c|c|}x&y\\-8&-7\\0&0\\8&7\\16&14\end{array}\right]$ $\begin{tabular}{|c|c|}x&y\\-8&-7\\0&1\\8&5\\16&4\end{array}\right]$
