uh oh- i messed that up bad...........
I think you had to work out the gradient of the second equation which was 6, and then use -1/6 as the gradient when you work out k because the question says normal.
Also, this may seem dumb, but I thought rational number meant mixed fractions. Would I lose a mark if I left my answer in mixed fractions in the 1st question?
Also what did everyone get for the last question?
The questions made sense however I just got to breaking point and froze on some questions because of the immense pressure. And now I just feel like that this is the final chapter.........................
And c= -12
