W- (3,4)
Z- (-1,1)
X-(-1,-3)
Y-(-4,1)
80%, 1000-200 = 800/1000 or 80%
Answer:
C) No, their slopes are not opposite reciprocals.
Step-by-step explanation:
First we find the slopes.
slope of PQ = (3 - 0)/(7 - 11) = 3/(-4) = -3/4
slope of RS = (-3 - 1)/(6 - 3) = -4/3
product of the slopes = (-3/4) * (-4/3) = 1
The slopes are reciprocals, but they are not opposite reciprocals, so the lines are not perpendicular.
I believe it would be b.
explanation: use this rule: (x^a)^b = x^ab
