There are several of these problems-all of which are very closely related. If someone could please get me started it would help me out alot. The problems are as follows:...

The point $\displaystyle P(5,37)$ lies on the curve $\displaystyle y=x^2+x+7$. If $\displaystyle Q$ is the point $\displaystyle (x, x^2 + x + 7 )$, find the slope of the secant line $\displaystyle PQ$ for the following values of $\displaystyle x$:

If x=5.1, the slope of PQ is:

Ohh Yea one other thing the formula for the slope of secant line is:

$\displaystyle m_{PQ} = \frac { y_{Q} - y_{P}}{x_{Q} - x_{P}}$

Thanks!
