ANS: 65, 37, or 17?

question 2.
what of the circle that has a diameter endpoints are (2,7) and -6-1)

3.
which of the following equation is of a parabola with a vertex at (0,-5)?

y=(x- 5) 2^, y= ( x+5)2^, y+ x2^-5, or y+ x 2^+5?

Answer 1

distance formula between (x1, y1) and (x2, y2) is:

sqrt((x1 - x2)^2 + (y1 - y2)^2)
