Question

The graphical representation of a pair of equation x+2y-4=0 and 2x +4y-12=0 represents​

Answer 1

Hi !

They represent straight lines

Hope this helps

Answer 2

Answer:

The above equation is taken from the chapter "Pair of linear equations in two variables "

Two solutions of each of the equations :

x + 2y – 4 = 0 ..................(1)

2x + 4y – 12 = 0...............(2)

To represent the equations graphically, we plot the points R(0, 2) and S(4, 0), to get the line RS and the points P(0, 3) and Q(6, 0) to get the line PQ.

We observe in Fig. 3.4, that the lines do not intersect anywhere, i.e., they are parallel.

Figures are given in the above attachment.
