WebTo find where y=1/2x+5 and the original line y=-2x intersect, set them equal to each other. Let y in both of the equations equal the same value. You are doing this because at the two lines' point of intersection, both lines will share the same x and y value. So, let y=1/2x+5 equal y=-2x. That means. -2x = 1/2x+5.

How to determine if two lines are parallel? - GeeksforGeeks

WebParallel and perpendicular lines Parallel lines. Parallel lines are a fixed distance apart and will never meet, no matter how long they are extended. Lines that are parallel have the same gradient. Web1 Answer. Sorted by: 2. As long as the direction vectors are scalar multiples, the lines will be parallel. To show they are distinct, you need to show, for example, that ( 3, − 5, 10) is not on the first line. You'd need 3 = 2 − t, so t = − 1. Do the other coordinates match up? dunning zodiac pillow wayfair
