Answer:

  1.  -2+2x=y

Step-by-step explanation:

You only need to try the first two lines of the table to determine which equation works.

Only equations 1 and 4 work for the first line of the table (x=0).

  • 1.  -2 +2·0 = -2 . . . . . . . this works
  • 2.  2 -2·0 = 2 ≠ -2
  • 3.  2 +2·0 = 2 ≠ -2
  • 4.  -2 +0 = -2 . . . . . . . this works

Of those, only equation 1 works for the second line of the table (x=1).

  • 1.  -2 +2·1 = 0 . . . . . . . this works
  • 4.  -2 +1 = -1 ≠ 0

The equation that is true for the table values is ...

  -2 +2x = y
