Desmos Linear Regression to Find the Line of Best Fit

Описание: In this video, I walk you step-by-step through how to use Desmos to find the equation of a line of best fit from a scatter plot — a key skill for the Digital SAT Math section.
We’ll use sample SAT-style data points to calculate the slope (m) and y-intercept (b) automatically using Desmos’s linear regression feature.
You’ll also learn:
How to enter coordinate pairs correctly in a Desmos table
How to interpret the regression equation (y = mx + b)
How to match your equation to multiple-choice answers
Why the correct equation in this example is y = 13.5 – 0.8x
Perfect for students practicing data analysis and modeling questions on the Digital SAT!
