Y2-Y
It has a slope of zero because X2 - X, in the formula =
X₂ - X,
is zero, and the numerator of a fraction cannot be zero.
LS
y2-yi
It has a slope of zero because X2-X, in the formula m=
Xz - X, is zero, and the denominator of a fraction cannot be zero.
It has no slope because X2 - X, in the formula m-
42-4,
X2 - X, is zero, and the numerator of a fraction cannot be zero.
It has no slope because X2 - X, in the formula M=
Y2-4,
