The coordinaates of M and N are (-10,-7) and (5,8) respectively. P is a point on MN extended such that MN:MP=5:8. Find the coordinates of P.
點搵MN:NP 個ratio係幾多...?
ratio可唔可以好似+ -數咁- -?
e.g NP=MP-MN
=8=5
=3
THX
中三數 coordinate~section formula

✔ 最佳答案
點搵MN:NP 個ratio係幾多LetMN:NP 個ratio係r:1
Let P be (x,y)
x=(5(5)+8(-10))/(5+8)
y=(5(8)+8(-7))/(5+8)
