(x^2 - 3x - 10)(x + 4)
= (x - 5)(x + 2)(x + 4)
so the zeroes are (5,0), (-2,0) and (-4,0)

The number best describes the slope is positive 2
For this case you have the following advantages:
1) you can see the graph of both equations
2) you can see where the equations intersect
3) the point of intersection represents the solution to the system of equations.
4) You can solve the problem in much less time than doing it by hand
5) You can find very accurate solutions.
