A. Which two lines are parallel?
2 answers:
Step-by-step explanation:
line A and D are parallel because they have the same koeficient 3=3
line C is perpendicular to line A because
k1*k2=-1
3*(-1/3)=-1
which is a true statement
Answer:
a) Line D is parallel to line A
b) Line C is perpendicular to line A
Step-by-step explanation:
Line A has a slope of 3 and y intercept of 6
Line C is perpendicular to A as perpendicular lines have negative reciprocal slopes. Slope of C is -1/3
Line D is parallel to A as parallel lines have identical slopes but different y intercepts. Slope of D is 3 and y intercept is -1/3
Line B mirrors Line A over the y axis. It's slope is the negative of A and it has an identical y intercept.
