Few questions from my homework.

Find the equation of a circle with diameter endpoints (8,10) and (-2,14). I know I need to find the distance and midpoint but am having trouble with putting togther the exact formula.

2. Find the equation of a line in slope intercept form passing through (-2,-5) and (3,5)

And then find equation of a line that is parallel to the line above passing through (-3,4)

Functions:

How would you graph f(x)= sqaure root of x+2 - 3 Note: the 3 is not under the square root.

Explain what is being done to f(x) in this equation y=-2f(x+3)-1

How would you show that f(x)=8x^3 -3x is odd.

Thanks to anyone who can help me out.
