A linear equation has a constant rate of change so the independent variable x will only be to the first power. Any function with the variable raised to a power is non-linear (if it is squared there is a constant acceleration, if it is cubed there is a constant thrust, etc...)

In this case only c. has x raised to a power other than one.

Hmmm, write/type down the question on here so, I can read it better and solve it out or ask for help from my teacher, but it looks pretty easy for me even though I'm Middle School.

For each diagram, describe a translation, rotation, or reflection that takes line ℓ to line ℓ′. Then plot and label A′ and B′, t

Answer:

translate down 3
reflect across the horizontal line through A

Step-by-step explanation:

1. There are many transformations that will map a line to a parallel line. Translation either horizontally or vertically will do it. Reflection across a line halfway between them will do it, as will rotation 180° about any point on that midline.

In the first attachment, we have elected to translate the line down 3 units.

2. Again, there are many transformations that could be used. Easiest is one that has point A as an invariant point, such as rotation CW or CCW about A, or reflection horizontally or vertically across a line through A.

Any center of rotation on a horizontal or vertical line through A can also be used for a rotation that maps one line to the other.

In the second attachment, we have elected to reflect the line across a horizontal line through A.
