Answer:
(-9, π/5 + (2n + 1)π)
Step-by-step explanation:
Adding any integer multiple of 2π to the direction argument will result in full-circle rotations, which are identities, so this family is equivalent to the give coordinates:
(9, π/5 + 2nπ), for any integer n
Also, multiplying the radius by -1 is a point reflection, equivalent to a half-turn rotation. Then add π to the direction for another half turn, and the result is another identity. So this too is equivalent to the given coordinates:
(-9, π/5 + (2n + 1)π), for any integer n
Answer:
The slope of the line is -3.
Step-by-step explanation:
The slope equation is:
m= y2-y1/x2-x1
In this case:
m= -3-6/2+1 (remember that a negative minus a negative gives you a positive)
Which equals:
m=-9/3
Divide and you get -3.
7a) 302.5
7b) 302500

Answers: 
1. Switch sides

2. Subtract by 8 from both sides of equation.

3. Simplify.

4. Multiply by -1 from both sides of equation. (it's should be the reverse inequality).

5. Simplify.

6. Then you had to divide by 9 from both sides of equation.

7. Simplify.

8. Divide by the numbers.
