In the table, I can spot this relationship between 'x' and 'y':
'x' is multiplied by 3 and subtracted by 7 to get 'y':
[tex]\sf -8\cdot 3=-24-7=-31[/tex]
[tex]\sf 4\cdot 3=12-7=5[/tex]
[tex]\sf 7\cdot 3=21-7=14[/tex]
[tex]\sf 12\cdot 3=36-7=29[/tex]
We can write this as an equation:
[tex]\boxed{\sf y=3x-7}[/tex]
