In y = mx + b form, the slope is in the m position and the y int is in the b position.
y = mx + b
slope(m) = -4
y int (b) = -5
y = -4x - 5
or
f(x) = -4x - 5
Its called amortization schedule
Fermat's little theorem states that

≡a mod p
If we divide both sides by a, then

≡1 mod p
=>

≡1 mod 17

≡1 mod 17
Rewrite

mod 17 as

mod 17
and apply Fermat's little theorem

mod 17
=>

mod 17
So we conclude that

≡1 mod 17
Answer: the similarity statement that expresses the relationship between the 2 triangles is the 3rd one.
Step-by-step explanation:
Regrouping is only done into lower place values. For example, tens to ones and hundreds to tens.
