The tangent to 
at the point (0, 5) has a slope equal to the derivative evaluated at 
.
This tangent passes through the point (0, 5), so its equation is
The normal line passes through the same point, but is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent. So the equation for the normal line is

Answer:
(x, y) = (1, -5)
Step-by-step explanation:
Using a graphing calculator to solve equations such as these is quick and easy. It is one of my favorite methods. The attached graph shows the solution is ...
(x, y) = (1, -5)
The number 0 is basically nothing, so 7 divided by nothing is not defined. That's why calculators or even the most powerful computer can't divide anything by 0
