How do you make. Two linear equations that are perpendicular to each other

In order to make two linear equations perpendicular to each other, we need to find the negative reciprocal of the slope.

In finding the negative reciprocal, we create a perfect 90° angle with the lines.

Example:

Given y = 2x + 3, find the perpendicular line.

2 -> -1/2

y = -1/2x + 3

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
