A. Distance between two points on a coordinate plane

Move pts. A & B so that AB (the distance between the 2 pts) is equal to EF. BUT you can't have the pts A & B line-up above or below pts E & F. You will fill in the table located below the grid. You will also answer some questions & make some observations

Table directions

If necessary first fill-in the facts for pts E & F[br]Then for your trys:[br]1. Each time place pts A & B so their distance will be equal to EF.[br]2. record their coordinates[br]3. calculate the ∆x & ∆y[br]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 ∆y for the pair of pts. E and F or the pair of pts A 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 horizontal line? Explain.
