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...
The point of intersection of perpendicular lines is called the foot of the perpendicular. Properties of perpendicular lines. These lines always intersect at right angles. If two lines are perpendicular to the same line, they are parallel to each other and will never intersect.
- 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...
- 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...
A General Note: Parallel and Perpendicular Lines. Two lines are parallel lines if they do not intersect. The slopes of the lines are the same. f (x) =m1x+b1 and g(x) =m2x+b2 are parallel if m1 = m2 f (x) = m 1 x + b 1 and g (x) = m 2 x + b 2 are parallel if m 1 = m 2. If and only if b1 = b2 b 1 = b 2 and m1 = m2 m 1 = m 2, we say the lines ...
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.
For example, if the equations of two lines are given as, y = -3x + 6 and y = -3x - 4, we can see that the slope of both the lines is the same (-3). Therefore, they are parallel lines. 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.

They have the same slope. Properties of Perpendicular Lines. Perpendicular lines always intersect at an angle of $90^{\circ}$. All perpendicular lines are intersecting lines, but all intersecting lines are not perpendicular because they need to intersect at right angles. The product of slopes of two perpendicular lines is $-1$.
