Thread: [SOLVED] equation

Hello,

i 've an exercice to do but i'm quite perplexed, can u help me ?!
i 've beginning this graphic :



EX:

Points D1,D2,D3,D4 are in a graphical and their equations are y= 10,y=4,y=2 and y=8
A is an other point with A(4;10)
Can we find points B,C,D on D2,D3 and D4 so that ABCD is a rhombus.

Hello, jadee!

Your explanation is confusing.
I think I've translated it . . .

We have a point A(4,10).

and four horizonal lines: .


Find points on so that is a rhombus.

Code:

          |       (4,10)
        10+ - - - - o - - - - - - - - - -
          |        * A  *
          |       *         *   B
         8+ - - -*- - - - - - - o (b,8) -
          |     *              *
          |  D *              *
         4+ - o - - - - - - -*- - - - - -
          | (d,4) *         *
          |           *  C *
         2+ - - - - - - - o - - - - - - -
          |             (c,2)
          |
    ------+--------------------------------
          |

We must determine so that: .

Am I close?

thx!
