Weby = m1x + b1. y = m2x + b2. then the slopes are m 1, m 2 and the y-intercepts are b 1, b 2. To show that two lines are parallel, we need: m1 = m2 ( the two lines have the same slope) b1 != b2 (the two lines have different y-intercepts) Let’s look at some examples. WebDec 21, 2015 · Parallel lines to this would have the same slope, 1/6 as well. The equations to those lines would then be y = 1/6x + b, where b could be any y-intercept. This is because no matter how much you move the parallel line up or down, its slope will be the same so it …

Using Slopes to Prove Lines Are Parallel or Perpendicular

WebJan 11, 2024 · Two lines are parallel if they never meet and are always the same distance apart. Both lines must be coplanar (in the same plane). To use geometric shorthand, we write the symbol for parallel lines as two tiny parallel lines, like this: ∥∥. For example, to say line JIJI is parallel to line NXNX, we write: JI\parallel NX J I ∥ NX WebWe can say that abd=bdc because the line he drew through the parallelogram is technically a transversal. Because it is a transversal, the two angles it forms are congruent, since we already know that the lines are parallel to each other.
