(-3,2) is solution of​

Answer 1

This answer clears your concept.

See,

Each equation have a line .

Each coordinate have a unique point .

So , coordinate (-3,2) will have a point on graph too .Now, infinite lines can pass through a point .

Each line here represent a equation , so there are infinite equations for (-3,2)

Some of them are:

x+y= -1

-x + y = 5

10x + 15y = 0
