Final answer:
Formula Rearrangement is the mathematical technique that involves manipulating an equation to isolate a particular variable and determining the slope of a line.
Step-by-step explanation:
The mathematical technique that involves manipulating an equation to isolate a particular variable and determining the slope of a line is called Formula Rearrangement. This technique allows you to rewrite a formula so that a variable of interest is on one side of the equation. The slope of a line is found by examining the coefficient of the variable that represents the dependent variable.
