In summary, the conversation is about a problem involving finding points with a y-coordinate of -3 that are a distance of 13 from the point (1,2). The solution involves finding the x-coordinate using the Pythagorean theorem and the conversation ends with a question about the relevance of the problem in the forum.

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?

1. What is a graph?

A graph is a data structure that is used to represent relationships between objects or data points. It consists of nodes (vertices) connected by edges (lines) that show the connections between the nodes.

2. What is a graph problem?

A graph problem is a mathematical problem that involves finding a solution or making predictions based on data represented in a graph. This can include tasks such as finding the shortest path between two nodes, determining the most efficient route, or identifying patterns in the data.

3. How do you create a graph?

A graph can be created by first determining the data points or objects that need to be represented, and then drawing the nodes and edges accordingly. There are also various software tools and programming languages that can be used to create graphs programmatically.

4. What are the different types of graphs?

There are several types of graphs, including directed and undirected graphs, weighted and unweighted graphs, and cyclic and acyclic graphs. Some common examples include bar graphs, line graphs, and pie charts.

5. How can graphs be useful in scientific research?

Graphs can be very useful in scientific research as they allow researchers to visualize and analyze data in a more intuitive and comprehensive way. They can help identify patterns, trends, and relationships that may not be apparent from just looking at raw data. Graphs are also helpful for making predictions and communicating research findings to others.
