A scatter plot is made to model the amount of money left to pay on a mortgage. The data used for the scatter plot are shown in the table: What does the y-intercept of the model represent?
A. The amount of the mortgage that has been paid that month
B. The monthly payments
C. The original amount of the mortgage
D. The number of months it takes to pay off the mortgage

okay wait before i answer, is this for your points on a graph?

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
