is the answer D?

phi · Answer

yes, 4 is the slope of this line

next, we use this fact:  the slope of a line perpendicular
is the "negative reciprocal"

that means  write the slope as a fraction  4/1  (in this case)
"flip" the fraction
then multiply by -1  i.e. make it negative

what do you get ?
