2.(ii)  Give the geometric representations of 2x + 9 = 0 as an equation

    (ii) in two variables

Answers (1)

For 2 variable representation of 2x + 9 = 0.

  Equation :     2x +0.y =-9

   For graph, 

     y=0,we have x=\frac{-9}{2}        

     y=1,we have  x=\frac{-9}{2}  

     y=2,we have x=\frac{-9}{2}    

Hence, (\frac{-9}{2},0) ,   (\frac{-9}{2},1)and    (\frac{-9}{2},2)  are solutions of equation.
