Answer:
D) -3/4
Step-by-step explanation:
Slope is found by using
m= (y2-y1)/(x2-x1) hwere the points are (x1,y1) and (x2,y2)
= (-3-3)/(3--5)
= (-6)/(3+5)
= -6/8
=-3/4
Vocab:
Parallel = same slope
Perpendicular = opposite sign and reciprocal slope
-5/2 opposite and reciprocal = 2/5
Solution: they are perpendicular
You treat is like an equation but keep the inequality sign
So
2y<-18+8
2y<-10
y<-5
