## Move points C & B so that CB (the distance betw the 2 pts) is equal to EF. BUT you can't have the pts C & B line-up to the right or left of pts E & F. You will fill in the table located below the grid. You will also answer some questions & make some obse

## Table directions

If necessary first fill-in the facts for pts E & F
Then for your trys:
1. Each time place pts C & B so their distance will be equal to EF.
2. record their coordinates
3. calculate the ∆x & ∆y
4. calculate/determine their distance.

## Short answer.

1. The symbol ∆x means "change in x". Explain how we calculate the ∆x and include an example in your explanation (not an ex. you have been provided with).

## Short answer.

2. The symbol ∆y means "change in y". Explain how we calculate the ∆y and include an example in your explanation (not an ex. you have been provided with).

## short answer

3. The ∆x for the pair of pts. E and F or the pair of pts C and B was always equal to zero, explain why. Are there any useful take aways?

## Short answer

4.Is there another way to get the distance between two points on a coordinate plane when the points lie along a vertical line? Explain.
