Question

A liner equation is always a function unless it’s a vertical line.

True
False

Answer 1

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.

Answer 2

It's true

Step-by-step explanation:

Because unless x is vertical, the slope will not have more than one y-value for each x-value.
