Question

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

Answer 1

Find the negative reciprocal of one slope.

Example:

y=4x+12

the negative reciprocal of 4 is -1/4

the perpendicular equation would be y= -1/4+12

Answer 2

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
