Which equation is true for the three pairs of x- and y- values in the table
1 answer:
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
