I'd really appreciate it if anyone ! : ) which statement best explains why y=4−6x is a function? it is a linear equation. the solutions to the equation can be written as ordered pairs. the slope is a factor of the y-intercept. each x value has one and only one y value.

Each x value has one and only one y value.

Step-by-step explanation:

y = f(x) can be called a function if, and only if

f(a) = f(b) means that a = b.

That is, each x value has one and only one y value.

y = 4 - 6x

f(a) = f(b)

4 - 6a = 4 - 6b

6b = 6a

b = a

So the correct answer is:

Each x value has one and only one y value.
