Step-by-step explanation:
I will attach a file with the graph of the rectangle and the lines of reflection.
We know that RSTU is a rectangle with vertices at ,
,
and
The first step is to draw the vertices on the plane and them the rectangle.
The rectangle is a symmetrical figure. Therefore if we want to carry the rectangle onto itself using a line of reflection this line must goes through the centroid of the rectangle.
Given that we have a rectangle whose width is and its length is
its centroid will be place at
.
Looking at the graph and using this information we find that the two lines of reflection are and
.
Answer:
0
Step-by-step explanation:
Find the slope of a line going through points (-4,3) and (5,3) by calculating the ratio of the change in y to the change in x.
To do this I like to line up the points and subtract (this is finding the change). After doing so, you will put 2nd difference over 1st difference.
(-4 , 3)
-(5 , 3)
------------
-9 0
; this reduces to 0.
The slope is 0.
Slope is rise over run.
So if you had looked at the y's there was no change (0 change) while there was change in the x's. This means the line is horizontal since the graph isn't rising.
