If two nonvertical lines are parallel
WebTwo lines are parallel if they have the same slope or both are vertical lines. Two lines are perpendicular if either one of the lines is horizontal and the other is vertical or the product of their slopes is –1. Design the class lineType to store a line. WebParallel and Perpendicular Lines Perpendicular Lines Two nonvertical lines are perpendicular if their slopes are opposite reciprocals of each other. Vertical and horizontal lines are perpendicular. Example: Write an equation in slope-intercept form for the line that passes through (–4, 2) and is perpendicular to the graph of 2x – 3y = 9.

WebIf two lines are perpendicular what is the relationship between their slopes - Parallel lines have the same slope.. In other words, if m=ab, then m=ba.Apr. Math Help ... Theorem 105: If two nonvertical lines are perpendicular, then their slopes are opposite reciprocals of one another, or the product of their slopes is 1. Web27 dec. 2009 · So we can say that: Two nonvertical lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if their slopes are negative reciprocals of each...
Web7 okt. 2024 · Step-by-step explanation: Two nonvertical lines are parallel if and only if their slopes are equal and they have different y-intercepts. ... Find the slope and y-intercept of each line by writing their equations in slope intercept form. If the slopes are the same but the y-intercept are different, then the lines are parallel. Web10 jan. 2024 · Answer: D) If two parallel lines are cut by a transversal, then each pair of alternate interior angles is congruent. Step-by-step explanation: Since, By the Alternative interior angle theorem,. When two parallel lines are cut by the same transversal then the alternative interior angles made by the transversal on these parallel lines are congruent …
WebParallel lines have equal slopes. Conversely, if two different lines have equal slopes, they are parallel. If two nonvertical lines are perpendicular, then their slopes are negative reciprocals (actually, opposite reciprocals) of one another, or … WebAnswer (1 of 5): The relationship between the slopes of parallel lines is equality. Equality is an ‘equivalence relation’ therefore it has the three properties of equivalence relations: - The reflexive property: Any slope is equal to itself. - The symmetric property: If …
WebTwo nonvertical lines have slopes M1 and M2 respectively. The lines are parallel if blank and the blank are unequal. M1 times M2 = -1 or M1 =-1/M2 The lines are perpendicular …
