(0,4)(2,-3)
slope = (-3 - 4) / (2 - 0) = -7/2
-12c to the fourth power +18c to the third power! :)
Answer: 
<u>Step-by-step explanation:</u>
Rewriting the left hand side,
csc²t - cost sec t
= (1/sin²t)-(cost)(1/cost)
= 1/sin²t - 1
= 1/sin²t - sin²t/sin²t
= (1-sin²t)/sin²t
= cos²t/sin²t
= cot²t
Y= 18 because vertical angles are congruent.
