Final answer:
A linear equation is always a function unless it’s a vertical line.
Step-by-step explanation:
A linear equation is always a function unless it’s a vertical line. This statement is True.
A linear equation is an equation that represents a straight line on a graph. The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
For a linear equation to represent a function, every x-value must have a unique y-value. Vertical lines do not meet this criteria because they have the same x-value for every y-value, making them not functions.
