Answer:
Rotation of 180° about point B
<em></em>
Step-by-step explanation:
Considering coordinates of point B
Assume the coordinates of the line at point B is (x,y)
i.e.
First, we need to determine the slope at point B
Taking coordinates about the origin.
The slope of B is:
Where
--- origin
becomes
Taking the options one after the other:
Option A.
When rotated by 180°, the resulting coordinates of B would be
Taking the slope of B'
The slope of B is:
Where
--- origin
becomes
Notice that the slope of B and B' is the same;
<em>Hence:</em>
<em>Rotation of 180° about point B answers the question</em>

<em>There's no need to check for other options</em>
Answer:
With 3 3/8 cups of sugar Haley can make one and a half pie.
Step-by-step explanation:
The amount of sugar required to make each pie = 2 1/4 cup
Now,
So, Haley uses 2.25 cup of sugar foe each pie.
Total cups of Sugar Haley has = 3 3/8 cups.
Now,
So, the total amount of sugar Haley has is 3.375 cups.
Now,
=
or the number of pies she can make = 1.5
Hence, with 3 3/8 cups of sugar Haley can Make 1 1/2 pie.
