Find the equation of the line that is: parallel to y = 2x + 1. and passes though the point (5,4) The slope of y = 2x + 1 is 2. The parallel line needs to have the same slope of 2. We can solve it by using the "point-slope" equation of a line: y − y1 = 2 (x − x1) And then put in the point (5,4): y − 4 = 2 (x − 5)

Parallel lines are the lines that never intersect each other. Thus, two parallel lines always maintain a constant distance between them. Perpendicular lines are the two lines that intersect each other at a right angle. We come across examples of parallel lines and perpendicular lines in daily life. Observe the white lines or stripes in a marked ...
- Parallel lines are the lines which never intersect each other even if we extend them infinitely whereas intersecting lines meet each other at a point.
- No. Intersecting lines can meet at any angle. But all perpendicular lines are intersecting lines.
- The common characteristic is that both have straight lines.
- Yes. A figure can have both Parallel and Perpendicular Lines. Some examples are: Letter H, Letter E, Square, Rectangle etc.
- A rectangle has 2 pairs of parallel lines and 4 pairs of perpendicular lines.
Parallel and Perpendicular Lines. Parallel and perpendicular lines are an important part of geometry and they have distinct characteristics that help to identify them easily. Two lines are termed as parallel if they lie in the same plane, are the same distance apart, and never meet each other.
Aug 24, 2022 · The product of the two slopes is. m1m2 = 2 ⋅ (− 1 2) = − 1. Figure 3.5.11. Sketching perpendicular lines. Let's summarize: Parallel lines have the same slope m. Perpendicular lines have negative reciprocal slopes. That is, if a line has slope m, any line perpendicular to it must have slope − 1 / m.
Both lines have a slope m = 3 4 and thus are parallel. Perpendicular lines are lines in the same plane that intersect at right angles (90 degrees). Two nonvertical lines in the same plane, with slopes m1 and m2, are perpendicular if the product of their slopes is − 1: m1 ⋅ m2 = − 1. We can solve for m1 and obtain m1 = − 1 m2.
As with parallel lines, we can determine whether two lines are perpendicular by comparing their slopes. The slope of each line below is the negative reciprocal of the other so the lines are perpendicular. f (x) = 1 4x+2 negative reciprocal of 1 4 is −4 f (x) = −4x+3 negative reciprocal of −4 is 1 4 f (x) = 1 4 x + 2 negative reciprocal of ...
