Understanding Linear Expressions in Context

The video tutorial explains the linear expression 6X + 8, which represents the temperature of an oven over time. The variable X denotes the number of minutes elapsed. The tutorial clarifies that 6X is the variable part of the expression, as it changes with time, while the constant part, +8, remains fixed. The video helps viewers understand the distinction between variable and constant components in a linear expression.
