Answer:

Step-by-step explanation:
The first trinomial is

Let the other trinomial be P.
Then

We make P the subject to obtain,

We simplify to obtain,

Hence the other trinomial is 
So
100%=original
25% discount
100-25=75
it is 180 sale
75%=180
find 100%
a hack is to recognize that 75/3 times 4=100 so
75%=180
divide 3
25%=60
times 4
100%=240
the real way is proportions
75:180 =100:x
75/180=100/x
multiply both sides by 180x
75x=18000
divide 75
x=240
origitnal price=$240
I think you multiply 1/2 by the x and y point
1/2(0)= 0
1/2(-6)= -3
(0,-3)
