Understanding Linear Equations

The video tutorial from MooMooMath introduces linear equations and demonstrates how to check if a given point is a solution to a linear equation. The example equation y = -3x + 5 is used, with a focus on understanding the slope and y-intercept. The tutorial explains the process of verifying if the point (2, -1) lies on the line by substituting the x-value into the equation and checking if the resulting y-value matches. The video concludes by confirming that the point is indeed a solution, reinforcing the concept of solution verification for linear equations.
