Graphing Equations with Desmos

The video tutorial explains how to solve systems of equations using the graphing method with the Desmos graphing calculator. It covers graphing two systems of equations, identifying points of intersection, and recording solutions. The tutorial highlights the convenience of Desmos for entering equations and adjusting graph settings.

What is the primary goal when using the graphing method to solve a system of equations?

• To calculate the area under the curve

• To find the slope of each line

• To identify the points of intersection

• To determine the y-intercept of each equation

Which tool is used in the video to graph the equations?

• Microsoft Excel

• Desmos graphing calculator

• Google Sheets

• TI-84 Calculator

What setting is adjusted to make the graph more bold in Desmos?

• Clicking on the large capital A

• Changing the color scheme

• Increasing the line thickness

• Adjusting the brightness

What is the first equation entered into Desmos for the first system?
