Answer:
False.
Step-by-step explanation:
We have been given a statement. We are asked to determine whether our given statement is true or false.
We know that a line is function, when each value of x corresponds to exactly one y-value.
We can also test whether a line using vertical line test. If a vertical line intersects a line exactly at one place, then line represents a function. If a vertical line intersects a line more than once, then line is not a function.
A straight line on a coordinate plane does not always represent a function because vertical lines in form , where a is any real number, will fail vertical line test.
Therefore, our given statement is false.
