What is a linear equation

The video tutorial explains linear equations, which produce lines with constant rates of change. It covers different forms of linear equations, such as slope-intercept, standard, and point-slope forms. The tutorial also highlights the characteristics of linear equations, emphasizing that variables should not be raised to powers greater than one, appear in denominators, or be multiplied by each other. Non-linear equations are discussed as examples of what linear equations are not. The video concludes by reinforcing the properties of linear equations and their graphical representation.

What restrictions are placed on variables in a linear equation?

Explain why the equation y = x^2 + 1 is not a linear equation.
