Answer:
Graphical Method of solving pair of linear equations in two variables
----------------------------------------------------------------------------------------------------
Solution:
Given:
2x+3y-8=0...........................................(i)
i) For intersecting lines, a1 /a2 ≠ b1/b2
∴ Any line intersecting with eq i may be taken as
3x +2y -9=0 or 3x+2y -7 =0
ii) For parallel lines , a1 /a2 = b1/b2 ≠ c1/ c2
∴ Any line parallel with eq i may be taken as
6x +9y +7=0 or 2x+3y -12 =0
iii) For coincident lines, a1 /a2= b1/b2 =c1/c2
∴ Any line coincident with eq i may be taken as
4x +6y -16=0 or 6x+9y -24 =0
Question:
Concept:
To find the graph we have to first find the value of x and y...
Solution:
x|-1 | 2 | 5
——————
y| 2 | 4 | 6
(-1 , 2) (2 , 4) (5 , 6)
Plotting the value on the graph we get:
