Answer:
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
Find the negative reciprocal of one slope.
y=4x+12
the negative reciprocal of 4 is -1/4
the perpendicular equation would be y= -1/4+12
No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given
