I'm guessing this is a linear equation with input numbers? If it is, then I would first have to change the equation to point slope form: y = -3x + 4. Now heres a input table
Input | output for y | output for x* |
-2 | 10 | -2 |
-1 | 7 | -1 |
0 | 4 | 0 |
1 | 1 | 1 |
2 | -2 | 2 |
*output for x is the same as the input because m = 3/1, so x is only multiplied by 1.
