My translation was $(-8,2)$ but the generic statements don't explicitly tell me that my translation in $x$ is negative. Can you expand with further lines, stating e.g. the translation in x is distance 8 and in the negative direction, so the translation is -8. Or something along those lines.

Yes, either look at it again in Inkscape, or remove it.

One of the SVGs, graph_reflection_triangle_y-x_9Jed1Ac.svg, does not seem to exist.

I've made some small changes in the advice. You should use \mathrm{...} where you have words in the equations, such as "Volume". I've also made some further adjustments to the variable ranges.

Looks good.

This is looking good now. I would like to see the advice tabulated with columns for the word, definition and relevant example.

Christian's comment below, "I don't like how the choices are in a different order for each part", is still relevant for a couple of the gaps, which have common choices.

You need to think about the scale of your objects here. If you've gone to the effort of including a tennis ball then it would be a good idea not to give it a 30cm radius (unless it's one of those huge beach ones!). Same for the ice cream cone.
