The table shows a linear function (a) Determine the difference of outputs of any two inputs that are 1 unit apart. Show your work.

(b) Determine the difference of outputs of any two inputs that are 2 units apart. Show your work.

(c) Determine the difference of outputs of any two inputs that are 3 units apart. Show your work.

(d) What do you notice about the ratios of the differences in the outputs to the input intervals? Explain

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
