Discussion Overview

The discussion revolves around finding all points that have a y-coordinate of -3 and are 13 units away from the point (1,2). The scope includes geometric reasoning and distance calculations.

Discussion Character

  • Exploratory
  • Mathematical reasoning

Main Points Raised

  • One participant expresses difficulty in solving the problem and seeks assistance.
  • Another participant calculates the necessary x-coordinates based on the distance formula, concluding that the x-coordinates must be 13 or -11, assuming a two-dimensional plane.
  • A later post appears to repeat the initial request without contributing further to the mathematical discussion.

Areas of Agreement / Disagreement

There is no consensus on the solution, as the initial request for help remains unresolved, and the follow-up posts do not clarify or confirm the calculations presented.

Contextual Notes

The discussion lacks detailed exploration of the distance formula and does not address potential assumptions about the coordinate system or the nature of the problem.

I can't get the correct answer to this problem.

Find all points having a y-coordinate of -3 whos distance from the point (1,2) is 13.

Thank you!

Since the y difference is 5 (2-(-3)), the x difference must be 12 (52+122=132). The x coordinate must therefore be 13 or -11. (You've got 2 points - I am assuming we're working in a plane).

This is an elementary geometry problem. Why is it this forum?
