Answer:
8/-7
Step-by-step explanation:
using the equation: y₂-y₁/x₂-x₁

Answer:4
Step-by-step explanation:
you divide 72 by 18.
Negative exponents create the reciprocal of the original number:
2^2=4
2^-2=1/4
4^4=64
4^-4=1/64
Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф
