A table of values is shown below. x 2 4 6 8
y 12 8 4 0
What is the value of the y-intercept of the line represented by this table of values?

(60 points) explain this in detail

1. 2. ∠b and ∠y are right angles. 3.? 4.? which two statements are missing in steps 3 and 4? ∠x ≅ ∠c △abc ~ △zyx by the sas similarity theorem. ∠b ≅ ∠y △abc ~ △zyx by the sas similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem. = 2 △abc ~ △zyx by the sss similarity theorem.

Factor the polynomial by its greatest common monomial factor.
