Given,
……. (i)
……. (ii)
For equation (i),
⇒
When , we have
When , we have
Thus, we have the following table giving points on the line
a | ||
b |
From equation (ii),
We solve for a:
⇒
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:
From graph, it can be seen that the two lines intersect at .
Hence, the system of equations is consistent.
