Code Challenge 1.8 - Line Slope Calculator

Introduction

When graphing lines in Algebra, it’s important to understand how to calculate the slope of a line. To calculate the slope, at least two points must be identified. You can then calculate the slope using the Slope Formula. The Slope Formula is defined as:

where m is the slope, the ordered pair (x₁, y₁) is the first point, and the ordered pair (x₂, y₂) is the second point.

Skills to Practice

• Prompting a user for input
• Saving user input to variables
• Converting input to the correct data type (if necessary)
• Performing arithmetic calculations
• Formatting custom output using variables

Challenge Tasks

• Create a console project named Challenge 1-8.
• Prompt the user to enter four values corresponding to two points of a line i.e. (x₁, y₁) and (x₂, y₂).
• Calculate the slope using the Slope Formula.
• Optionally, round the answer to three decimal places.
• Display the calculated slope to the user in a clear and formatted manner.
