Question

show graphically that system of equation x+2y=5 , 3x+6y=15 has infinite many solution

Answer 1

The graphs of:

x + 2Y = 5

And

3x + 6y = 15

are the same, as shown in the attached image

Since these two graphs touch (intersect) at infinite number of points, it shows that the two equations have have infinite number of solutions.
