Jan 18, 2024 · The parallel to the line y = m × x + b passing through the point (p, q) can be found with the following steps: Find the slope of the parallel line — it's m! Find the intercept of the parallel line's equation substituting the coordinates of the point in the original line's equation: q = m × p + b Hence: b = q / (m × p)
Parallel Lines. Parallel lines are straight lines that run in the same direction and are always the same distance apart, ensuring they never meet, no matter how long they are extended. In terms of slopes, two lines are parallel if they have the same slope but different y-intercepts. The formula for slopes in this case is the following: $$ m_1=m ...

Two lines are perpendicular when they meet at a right angle (90°). To find a perpendicular slope: In other words the negative reciprocal
When we multiply a slope m by its perpendicular slope −1m we get simply −1. So to quickly check if two lines are perpendicular: Like this:
The previous methods work nicely except for a vertical line: In this case the gradient is undefined (as we cannot divide by 0): m = yA − yBxA − xB = 4 − 12 − 2 = 30= undefined So just rely on the fact that: 1. a vertical line is parallel to another vertical line. 2. a vertical line is perpendicular to a horizontal line (and vice versa).

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 ...
Apr 16, 2021 · Through the point \((6, −1)\) we found a parallel line, \(y=\frac{1}{2}x−4\), shown dashed. Notice that the slope is the same as the given line, but the \(y\)-intercept is different. If we keep in mind the geometric interpretation, then it will be easier to remember the process needed to solve the problem.
