For Number 12, you did the working and showed that the answer is -1/4 but you circled 1/4. Thank you so much for the video

Check number 23 again please~ I'm pretty sure it's choice D the gradient at (0, -3) should be -4/9 negative four ninths I checked this question with one of the AIs using GPT4 Copilot on the Microsoft Edge browser But it took quite a few follow up questions, until it agrees choice D is the correct line It would be great if you could confirm it~ Thanks for all your work on the pure math vids!

In the question i saw that in the second to third line it went from 0 - [0 + 4(-3)] to -12 when it should have been -(-12) which would have been +12 making the final part -12/27 which would be -4/9, I believe that is where he made the mistake and the correct answer should be D as u said

@@sapphireblues6947 thanks for confirming! I think this same question repeats, with choices re-arranged and he does put the line represented by choice D as the answer on that paper~ so in a way he confirms it too~

At number 13 you put 3/2 and on the 2020 paper you put root -3/2
