Step-by-step explanation:

NCr*P^r*q^(n-r)
7C4*. 75^4*. 25^(7-4)
35*. 75⁴*. 25³
35*. 316*. 016
11.06*. 016
. 1769
=. 177
We have the following equation:
y = 17x + 1
Substituting the point (1, 8) we have:
8 = 17 (1) +1
Rewriting:
8 = 17 + 1
8 = 18
We observe that the equation is not satisfied because both sides are different.
