The change of snowdrift from Thursday to Friday, as per linear equation, is -4 inches.
What is a linear equation?
A linear equation is an equation that has one or multiple variables. However, the highest degree of any variable is 1.
Given, from Monday to Thursday, the depth of a snowdrift changed by -8 inches.
From Thursday to Friday, the depth of snowdrift changed by half as much.
If the depth of a snowdrift changed by x inches from Monday to Thursday, then the depth of a snowdrift changed by [tex]\frac{x}{2}[/tex] inches from Thursday to Friday.
Therefore, the depth of snowdrift changed from Thursday to Friday by [tex]\frac{-8}{2}[/tex] inches = -4 inches.
