Answer:
A) collinear
Step-by-step explanation:
"Parallel" and "perpendicular" are descriptors of pairs of lines and planes. They do not apply to pairs of points.
The two points have different coordinates, so are distinct, rather than coincident.
Of these words, the only applicable choice is "collinear."

<em>Additional comment</em>
<em>Any</em> pair of distinct points is collinear. Two points define a line, and two points on the same line are collinear.
Answer:
Step-by-step explanation:
You got 91% of the questions right out of 175. In math words, this is saying that:
![\frac{91}{100}*175=x](https://tex.z-dn.net/?f=%5Cfrac%7B91%7D%7B100%7D%2A175%3Dx)
![x=159.25](https://tex.z-dn.net/?f=x%3D159.25)
So, you got 175 - 159 = 15.75 questions wrong. The decimal could be from getting only part of a question wrong. So you got partial credit for one question
Let's say
P = perimeter, L : Length and w : width
Then
![P=2(L+w)=2L+2w=108](https://tex.z-dn.net/?f=P%3D2%28L%2Bw%29%3D2L%2B2w%3D108)
But
![L=6+2w](https://tex.z-dn.net/?f=L%3D6%2B2w)
So
![2L+2w=108\\2(6+2w)+2w=108\\12+4w+2w=108\\12+6w=108\\6w=108-12\\6w=96\\w=16](https://tex.z-dn.net/?f=2L%2B2w%3D108%5C%5C2%286%2B2w%29%2B2w%3D108%5C%5C12%2B4w%2B2w%3D108%5C%5C12%2B6w%3D108%5C%5C6w%3D108-12%5C%5C6w%3D96%5C%5Cw%3D16)
![L=6+2w\\L=6+2(16)\\L=6+32\\L=38](https://tex.z-dn.net/?f=L%3D6%2B2w%5C%5CL%3D6%2B2%2816%29%5C%5CL%3D6%2B32%5C%5CL%3D38)
We verify :
Length = L = 38Width = w = 16
