Answer 1

3

Explanation:

For it to be a linear function, then it obeys the general form of a liner equation which is y = mx + c

Where m represents the slope and c represents the y intercept

Now let’s take the last point on the table;

and substitute the values of x and y;

we have;

10 = 2m + c. ••••••••(i)

let’s take the second to the last;

7 = m + c ••••••••••(ii)

So let’s solve both equations simultaneously

Just subtract second from first directly

This gives m = 3
