Question

Could you answer number 4 for me please i don't get it ?

Answer 1

In the table, I can spot this relationship between 'x' and 'y':

'x' is multiplied by 3 and subtracted by 7 to get 'y':


`\sf -8\cdot 3=-24-7=-31`

`\sf 4\cdot 3=12-7=5`

`\sf 7\cdot 3=21-7=14`

`\sf 12\cdot 3=36-7=29`

We can write this as an equation:


`\boxed{\sf y=3x-7}`
