How can I calculate the slope of segments given the coordinates?

I did linear fit on the data, and I obtained five segments (AB, BC, CD, DE and EF) with X1 and Y1 vector (coordinates for the segments). I want to calculate the slope of each segment with the data contained in the X1 and Y1:
%slopes=(y2_y1)./(x2-x1);
for i=1:size(YI,2);
y(:,1) = YI(2,2)-YI(1,1);
end
for i=1:size(XI,2);
x(:,1) = XI(2,2)-XI(1,1);
end
slopes=y/x;

slopes = y./x;
