Answer 1

The equation that matches the table is b = a + 4.

Step-by-step explanation:

The equation that matches the table is b = a + 4. We can see that when the value of a is 4, the value of b is 8, and when the value of a is 8, the value of b is 12. This shows that b increases by 4 when a increases by 4, which matches the equation b = a + 4.
