Is the line through (-2, 3) and (4, 1) perpendicular to the line 3x = y + 1 ?
Does the line 3x = y + 1 bisect the join of (+2, 3) and (4, 1) ?

Answer:
yes both lines would be perpendicular..
because slope of 1st line is the negative reciprocal of other...
now coming to 2nd question....
No it doesn't cuz the midpoint ain't satisfying the equation of other line..
