Hello!

Today we used coordinates to determine the distance between two points.

Here is the distance formula:


Use the coordinates provided to answer  the questions below:

If you need a calculator, you can use this!  (To square^2 an answer, you use the xy button--> type the number, then xy button, then 2)

Level 1: 

Point 1 : (1, 9)
Point 2: (7, 18)

What is:
X1:
X2:
Y1:
Y2:


Level 2: 

Point 1 : (-2, 14)
Point 2: (7,19)

Part A: What is...
X1:
X2:
Y1:
Y2:

Part B:
What is (X2 - X1)^2 =
What is (Y2 - Y1)^2 =


Level 3: 

Point 1 : (-13, -7
Point 2: (15, 20)

Part A: What is...
X1:
X2:
Y1:
Y2:

Part B:
What is (X2 - X1)^2 =
What is (Y2 - Y1)^2 =

What is the sum of of part B:
