To find the perpendicular slope of a line, just reciprocate its slope, and for finding the line parallel to it, according to purplemath.com:
"In numbers, if the one line's slope is m = 4/5, then the perpendicular line's slope will be m = –5/4. If the one line's slope is m = –2, then the perpendicular line's slope will be m =1/2. To answer this question, I'll find the slopes. Since these two lines have identical slopes, then these lines are parallel<span>."
I hope my answer has come to your help. God bless and have a nice day ahead!

Answer:
your answer is 18
Step-by-step explanation:
Answer:
A. Three points
Step-by-step explanation:
Tangent circles will intersect at the one point of tangency.
Circles that cross each other will intersect in two points.
Circles that are coincident will intersect in infinitely many points.
It is not possible for two circles to intersect in exactly 3 points.
