    there is this question and it doesnt tell much information...
    here it is:
    find the gradient of the line 1(<-- written in itallics if anyone was interested) which has equation x+2y=4.

    i dont understand this at all!

      Could it be the letter L in lowercase? Looks to me to be a very simple question unless I'm having a special moment and have missed something blindingly obvious.

      Well the most likely thing is that further on in the question they will introduce a second line and hence call it Line 2. Although I guess it is fairly confusing, as usually they'd use Line A, or somehting, but that's my best guess.

      nope it is clearly a 1.

      Basically, find the gradient of x+2y=4

      y=mx+c where m=gradient
      y=(-)1/2x+2

      therefore gradient = -1/2

      Think that's right.

      Yeah, I think (like the people above) that it is just a bit of a poorly written question... It probably means more lines are going to be introduced later on.

      They're calling that line, the line '1'. It's like having a baby and then giving it a name ... and you have to find the gradient of that baby.

      The '1' means that its 'line 1(one)'. Its just a name for the line which you've gotta work out the gradient of. The '1' isn't used in the actual calculation of the question.

      \frac{\partial}{\partial{(baby)}  }(baby) = 1 :cool:
