Understanding Linear Equations

The video tutorial explains linear equations, focusing on the slope-intercept form y = mx + b. It covers the concepts of slope (m) as the constant rate of change and intercept (b) as the initial value. The behavior of lines is discussed based on the slope: positive slopes indicate increasing behavior, negative slopes indicate decreasing behavior, zero slopes result in horizontal lines, and undefined slopes lead to vertical lines. The tutorial analyzes four specific equations, identifying their constant rates of change, initial values, and behaviors.

What is the slope-intercept form of a linear equation?

• y = m + bx

• y = x + mb
