What is the slope of (-18,-20),(-18, -15)

Rzqust [24]

Answer:

Undefined.

Step-by-step explanation:

$m = \frac{rise}{run}$

$m = \frac{ - 15 - ( - 20)}{ - 18 - ( - 18)} \\ m = \frac{ - 15 + 20}{ - 18 + 18} \\ m = \frac{5}{0}$

The denominator is 0. Therefore, the slope is undefined.

Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = −1. (2 points)

umka2103 [35]

Focus of the parabola is (-5,5) and directrix is y = -1.

Let's assume a point (x,y) on parabola.

According to definition of parabola, the distance between point (x,y) and focus (-5,5) would be same as the distance between the point (x,y) and directrix y = -1.

$\sqrt{(x+5)^2+(y-5)^2} = \sqrt{(y+1)^2} \\\\(x+5)^2+(y-5)^2=(y+1)^2 \\\\(x+5)^2 + y^2 - 10y +25 = y^2 +2y +1 \\\\(x+5)^2 = -y^2 +10y -25 + y^2 +2y +1 \\\\(x+5)^2 = 12y -24 \\\\12y = (x+5)^2 +24 \\\\ y = \frac{1}{12} (x+5)^2 +2$

Hence, option D is correct, i.e. f(x) = one twelfth (x + 5)2 + 2.
