The 2 graded lines m1 and m2 are said to hold out parallel if m1 = m2 in addition to perpendicular if m1 ten m2 = -1
Example:
From unopen to of the business equations below, which are parallel in addition to intersect perpendicular!
Answer:
I in addition to II are parallel because the slope is the same, that is m = -2
I in addition to III, IV in addition to V intersect perpendicular, because of mI. mIII = -1 in addition to mIV. mV = -1.
Similarly this article.
Sorry if at that topographic point is a incorrect word.
