Hey this is vary simple question and can be done with in very less time..
Here we find that one of the equation is linear and an other is quadratic.

The quadratic equation represents a parabola and hence the curve appears like this. and the graph of the linear equation is also shown.

from the graph we find that both of them intersect at a single point that is (3,-3)
