.
Notice that the slope is zero because the two points have the same -coordinates (
) even though their
-coordinates are distinct (
.)
Equation for this line in point-slope form:
.
.
Rewrite and simplify to obtain the equation of this line in slope-intercept form:
.
The -term was eliminated because the slope was zero.
