Transcript of Find the distance between (-4, 2) and (6, -3). Find the midpoint of the segment connecting (3, -2)...
Find the distance between (-4, 2) and
(6, -3)
Find the midpoint of the segment connecting
(3, -2) and (4, 5).
The midpoint of a segment is (-5, 0) and one endpoint is (4, 3).
Find the other endpoint.
Find the focus:
y = 1/4(x – 3)2 – 6
2
Find the vertex:
y = 1/4(x – 3)2 – 6
2
Find the directrix:
y = 1/4(x – 3)2 – 6
2
Find the focus:
1/16 (y + 2)2 – 3 = x
2
Find the vertex:
1/16 (y + 2)2 – 3 = x
2
Find the directrix:
1/16 (y + 2)2 – 3 = x
