For the given circle, find the value of x and y

What is the length of the segment joining the points at (4,5) and (6,-2) round to the nearest tenth if necessary

Which of the following equations is of the parabola whose vertex is at (4, 3), axis of symmetry parallel to the y-axis and focus at (4, -3)? a.) y+3=1/24 (x+4)^2 b.)y-3=-1/24 (x-4)^2 c.)x-4=-1/24 (y-3)^2

With alll of except for the 2 that i did already
