EXPLANATION
For 
We make y the subject to obtain,

We can easily graph this function, because we just have to transform the graph of
by shifting the intercept up to
.
As for the straight line,
,
We find the intercepts as follows,
When
.
When
.
We plot the points
and
.
We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be
