Question

Which statement best explains why y=4−6x is a function?

Question 3 options:


It is a linear equation.


The slope is a factor of the y-intercept.


Each x value has one and only one y value.


The solutions to the equation can be written as ordered pairs.

Answer 1

The correct answer option is: Each x value has one and only one y value.

Explanation:

A relationship from a set of inputs to a set of outputs where each input has exactly one corresponding output value is said to be a function.

Here, we are given
`y=4-6x` which happens to be a function as no x value is repeated and there is only one corresponding y value to it.

Therefore, option c is the correct answer.
