Emily is a salesperson who sells computers at an electronics store. She is paid a $1.25 commission for every computer sale she makes and she also makes a guaranteed base
pay of $80 each day. Make a table of values and then write an equation for P, in
terms of x, representing Emily's total pay on a day on which she sells r computers.

0 computers sold = 80.00

1 computer sold= 81.25

2 computers sold= 82.50

3 computers sold 83.75

P = 1.25x+80

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
