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)

The perpendicular lines are two lines that intersect each other and the angle formed between the two lines should be equal to 90 degrees (right angle). Consider the above-given figure, the line PQ and RS forms a right angle when the lines intersect at a point. Hence, the lines are perpendicular to each other and mathematically it is represented ...
- Perpendicular lines are those lines that intersect each other at 90 degrees.
- Parallel lines are parallel to each other and never intersect. But perpendicular lines intersect at right angle.
- Not all intersecting lines are perpendicular to each other. They may intersect at different angles too.
- If the slope of perpendicular lines are m1 and m2, then; m 1 .m 2 = -1
- Given, equation is y = -4x + 9 So, the slope of the given equation is -4. Now the slope of the lines perpendicular to the given line is: m = neg...
So we can say this: When a line is perpendicular to two lines on the plane (where they intersect), it is perpendicular to the plane. It will also be perpendicular to all lines on the plane that intersect there. And there is a lot more we can say: Through a given point there passes: one and only one line perpendicular to a plane.
Two distinct lines intersecting each other at 90 ∘ or at a right angle are called perpendicular lines. Example: Here, AB is perpendicular to XY because AB and XY intersect each other at 90 ∘. Non-Example: The two lines are parallel and do not intersect each other. The two lines are intersecting each other at an acute angle.
- We can define a perpendicular line as two straight lines joined to a common point making a $90^{\circ}$ angle with each other. Perpendicular lines...
- These lines always intersect at right angles.
- The perpendicular symbol is $\left|\right|$. It is used between the two lines to show that they are perpendicular to each other.
- Perpendicular lines intersect at right angles (90 degree) while parallel lines are parallel to each other and never intersect. Graphically, paralle...
- No, not all intersecting lines are perpendicular to each other. They may intersect at different angles other than 90 degrees.
- Parallel lines never touch each other while perpendicular lines meet each other at the intersecting point. Thus, you cannot have two lines that are...
Parallel lines and their slopes are easy. Since slope is a measure of the angle of a line from the horizontal, and since parallel lines must have the same angle, then parallel lines have the same slope — and lines with the same slope are parallel. Perpendicular lines are a bit more complicated. If you visualize a line with positive slope (so ...
Mathematically, this can be expressed as m 1 = m 2, where m 1 and m 2 are the slopes of two lines that are parallel. Perpendicular lines do not have the same slope. The slope of one line is the negative reciprocal of the other line. This can be expressed mathematically as m 1 × m 2 = -1, where m 1 and m 2 are the slopes of two lines that are ...

Given the equations of two lines, this gives a method to test whether the two lines are perpendicular. This also gives us a way to find equations of lines that are perpendicular to another line. In the 2-dimensional plane, given a fixed line and any point on the line, there is exactly one line passing through this point and perpendicular to the original line.
