Let's determine if multiplying the parent linear function by -1 results in a results in a reflection in the x-axis.

A reflection over the x-axis means the line is reflected over the horizontal axis.

When a linear function is multiplied by -1, the line will be reflected over the x-axis.

Take the function as an example:

y = 5x + 1

Here, we have the point:

(x, y) ==> (1, 6)

When the function is multiplied by -1, we have:

y = -5x - 1

Here, we now have the point:

(x, y) ==> (1, -6)

By applying the reflection rule for a reflection over the x-axis:

(x, y) ==> (x, -y)

We can say that multiplying the parent function by -1 results in a reflection in the x-axis.

ANSWER:

True
