Find the two horizontal and two vertical tangent lines of the equation x^2+xy+y^2=9.

valina [46]

Differentiating w.r.t y,
We get,

2 x (d x/d y) + y (d x/d y) + x + 2 y = 0 

Put
d x/d y = 0 

The equation becomes:
x=2 y 

substituting into main equation

We, get

3 y^2 =9 

y= √3

x = ± 2√3

Find the slope of the line through the pair of points. A(2, –3), P(2, 9)

Flauer [41]

The slope: $m=\dfrac{y_2-y_1}{x_2-x_1}$

$A(2;-3)\to x_1=2;\ y_1=-3\\P(2;\ 9)\to x_2=2;\ y_2=9\\\\subtitute:\\\\m=\dfrac{9-(-3)}{2-2}=\dfrac{12}{0}!!!$

The denominator can not be zero!

Conclusion: The slope is undenfined.
