Area of qudrilateral from input vertices (condition error when 3+ points on the same line)

Hello everyone, I want to implement a condition for the while loop where after checking some other details (vytest), it will check if at least one of the last two vertices (C, D) are on top of the line drawn by the first two (A, B).
else
coef(cnt,:)=polyfit([vx(1) vx(cnt)], [vy(1) vy(cnt)], 1);
while vytest==0||(vy(cnt)==coef(cnt,1)*vx(cnt)+coef(cnt,2) && vy(cnt-1)==coef(cnt-1,1)*vx(cnt-1)+coef(cnt,2))
if vytest==0
fprintf('ERROR: no1\n');
else
fprintf('ERROR: no2\n');
end
temp = input(' Y=');
vytest=isnumeric(temp);
vy(cnt) = temp;
end
end
As to this point I have done the above but with no error turning up when inserted 3+ points of the same line.
A=[vx(1) vy(1)]
B=[vx(2) vy(2)]
C=[vx(3) vy(3)]
D=[vx(4) vy(4)]
and
cnt=1:4
Thanks very much in advance!!

Yes, when you use degree 1, in polyfit; the first one would be a and second one is b.
