Finding Intercepts and Using Desmos

This tutorial provides a step-by-step guide on using Desmos to graph linear equations and find X and Y intercepts. It explains how to input equations into Desmos, either on a computer or a phone, and demonstrates the process with example equations. The tutorial highlights the ease of identifying intercepts by tapping on them to get coordinates, making it accessible for both desktop and mobile users.

What is the primary function of Desmos as introduced in the tutorial?

• To create 3D models
