Given,
……. (i)
……. (ii)
From equation (i),
⇒
When , we get
When , we get
Thus, we have the following table giving points on the line
a | ||
b |
From equation (ii),
Solve for b:
⇒
So, when
And, when
⇒
Thus, we have the following table giving points on the line
a | ||
b |
Graph of the equations (i) and (ii) is as below:
Thus, the from given graph of the two equations are coincident. Hence, the system of equations has infinitely many solutions.
