What is the answer to the math problem. and avoid asking rhetorical questions.

ask friendly, clarifying questions.
don't set traps.
ask open-ended questions.
be grateful.
avoid stress.
avoid being too direct.
silence is golden.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
