Math Problem Statement

Find the distance between each pair of points. Round your answer to the nearest tenth, if necessary.

Solution

Let's calculate the distance between each pair of points in the given graphs using the distance formula:

d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

I will analyze the points from each graph:

For Graph 1:

  • Points: (-2, 3) and (3, -1)

d=(3(2))2+(13)2d = \sqrt{(3 - (-2))^2 + (-1 - 3)^2}

d=(3+2)2+(13)2d = \sqrt{(3 + 2)^2 + (-1 - 3)^2}

d=52+(4)2d = \sqrt{5^2 + (-4)^2}

d=25+16=416.4d = \sqrt{25 + 16} = \sqrt{41} \approx 6.4

For Graph 2:

  • Points: (-4, -2) and (2, 2)

d=(2(4))2+(2(2))2d = \sqrt{(2 - (-4))^2 + (2 - (-2))^2}

d=(2+4)2+(2+2)2d = \sqrt{(2 + 4)^2 + (2 + 2)^2}

d=62+42d = \sqrt{6^2 + 4^2}

d=36+16=527.2d = \sqrt{36 + 16} = \sqrt{52} \approx 7.2

Final Answers:

  1. Graph 1: Distance = 6.4 (rounded to the nearest tenth)
  2. Graph 2: Distance = 7.2 (rounded to the nearest tenth)

Would you like me to explain any steps in detail or calculate something else? Here are some follow-up questions:

  1. Can you identify where the distance formula is derived from?
  2. Would you like a graph or visualization of these calculations?
  3. Should I explain how to approximate square roots?
  4. Do you need help generalizing this formula for 3D space?
  5. Would you like to verify these calculations with another method?

Tip: When finding distances, always carefully substitute the coordinates to avoid sign errors.
