The slope of the given line is 1/3.

The perpendiculars all have the negative reciprocal slope, -3.

<span>A. y + 2 = -3(x-4)

Yes, slope -3.

B. y - 5 = 3(x+11)

No, slope 3.

C. y = -3x - 5/3

Yes, slope -3.

D. y = 1/3  x - 2

No, that's slope 1/3.

E. 3x + y = 7
</span>
That's

y = -3x + 7

Another slope -3, Yes.

Question 1:

This is a 45-45-90 right triangle. If the leg length is x, then the hypotenuse length will be x \sqrt{2}.

The leg length of this 45-45-90 right triangle is 8. Multiply that with the square root of 2. You get 8 \sqrt{2}. Thus, the last choice is your answer.

Question 2:

This triangle can be identified as a 30-60-90 right triangle.
Let's say the smallest leg as a length of x.
Then, the longer leg will have a length of x \sqrt{3}.
Also, the hypotenuse will have a length of 2x

This triangle follows this format, making it a 30-60-90 right triangle. Thus, the angles are 30, 60, and 90.

Hope this helps! :)

Read below

Step-by-step explanation:

(2)2(−4)3. (2)3 +(−4)2. Substitute 2 for x and −4 for y. 4(−64). 8+16. = −256 ... An equation is a term used to describe a collection of numbers and variables related ... gives us a set of coordinate points that we can plot to create a graph of the function. ... The tick-marks on the number line represent evenly spaced integers.
