For the graph y = 12 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with with two or more sentences

Respuesta :

y = 12 is a horizontal line, parallel to the x- axis , hence has slope of zero

The slope of a line parallel to it will also be zero, as parallel lines have equal slopes

The slope of a line perpendicular to it, is the slope of a vertical line which is undefined or has no slope
