the line whose equation is y+=+4x+%2B+12 have a slope m=4
that is perpendicular to the line above will have a slope negative reciprocal and it is m%5Bp%5D=-1%2F4
then, equation that represents a line that is perpendicular to the line whose equation is y+=+4x+%2B+12 is
y+=+-%281%2F4%29x+

Which equation? What are the available choices? Infinitely many lines in the plane are perpendicular to y=4x+12. They all will have slope -1%2F4.

Here a just a few examples of such lines perpendicular to y=4x+12:
