In the figure below, all the points are evenly spaced along the line. What is the coordinate of point A?
-10, -9, -1, 0?

The answer to your question is -1

Step-by-step explanation:

Data

-Find the coordinate of point A

Process

1.- Find the distance between point B and point E

     dBE = 26 - 8

     dBE = 18

2.- Find the coordinate of point L

Point L must be in the middle between B and E

         L = 8 + 18/2    

         L = 8 + 9

         L = 17

3.- Find the coordinate of point A

         A = 8 - 9

         A = -1

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
