Answer:

  • x = - 4

Step-by-step explanation:

The slope is the ratio of rise to run.

Rise is the difference of y-coordinates, run is the difference of x-coordinates.

Now, the slope is said undefined if the difference of x-coordinates is zero.

It means you have to divide by zero but it is impossible.

We have a point (- 4, - 8) and the slope is undefined.

It means our line has repeat x = -4 coordinates, it is a vertical line.

<u>Its equation will be:</u>

  • x = - 4

Let's write the equation

  • m=undefined
  • Point (-4,-8)

\\ \sf\longmapsto y=mx+b

  • Line is parallel to y axis

\\ \sf\longmapsto x+4=\dfrac{-8}{\infty}

\\ \sf\longmapsto x+4=0

\\ \sf\longmapsto x=-4

Simplify the trigonometric expression.
Natasha_Volkova [10]
First we are going to find the common denominator of both fractions. To do that, we are going to multiply their denominators:
(1+sin \alpha )(1-sin \alpha )=1-sin^2 \alpha

Now we can rewrite our expression using the common denominator:
\frac{1-sin \alpha }{1-sin^2 \alpha } + \frac{1+sin \alpha }{1-sin^2 \alpha} = \frac{2}{1-sin^2 \alpha}

Finally, we can use the trig identities: 1-sin^2 \alpha =cos^2 \alpha and sec \alpha = \frac{1}{cos \alpha } to simplify our trig expression:
\frac{2}{cos^2\alpha}=2sec^2 \alpha

We can conclude that the correct answer is the fourth one.
