How do you find the perpendicular line of an equation
Finding the perpendicular line of an equation:
If two lines are perpendicular to each other, then they meet at right angles (i.e. degrees)
To check whether the two lines are perpendicular, multiply their slopes.
If the product of the slope is equal to then the given lines are perpendicular.
If is the slope of one line and is the slope of perpendicular line , then
Equation of perpendicular line through coordinate
For example, consider two line equations
The slope of the first equation is
The slope of the second equation is
Now, multiply two slope values,
Thus, the given equations are perpendicular to each other.
Hence, in this way we can find the perpendicular line of an equation.
