Answer:
B
Step-by-step explanation:
Perpendicular lines have opposite-reciprocal slopes
So if I had a slope of 2, the perpendicular slope would be -1/2.
Or if I had a slope of -7, the reciprocal is -1/7 and the opposite would be 1/7.
Hope this helps!

Answer:(-1.333, -.667)
Step-by-step explanation:
Graph shown below
Csc²x - 1
1/sin²x - 1
1/sin²x - sin²x / sin²x
(1 - sin²x) / sin²x
Recall that sin²x + cos²x = 1
So cos²x = 1 - sin²x
So we can replace numerator to cos²x
cos²x / sin²x
= cot²x
Final answer: cot²x
