Pls i dont get this can someone pls explain it

If y=x that means that x and y should be the same

Step-by-step explanation:

For example, if you look at the table you will see that there is a 2. Fill the 2 in the equation. Since the 2 is in the x column, it should be 2=y. This tells us that for the y column you can add a 2. So, the point is (2,2) When you continue doing that for the rest of the numbers, you may notice a pattern. The pattern is that both x and y are the same.

there are no short passages to look at
