Question

find the cordinates of point P which divides the directed line segment AB with corrdinates A(5,-2) and (9,6) in the ratio 3:1?

Answer 1

use ratio formula to solve this...do u knw what is ratio formula?

Answer 2

no srry

Answer 3

ratio formula is: x1k2+x2k1/k1+k2
here k1:k2=3:1 and also the points are given

Answer 4

0k thanks ill try to solve it

Answer 5

try to solve it...u just have to substitute the values of x1 x2 y1 y2 and k1 and k2

Answer 6

would it look like this ?
(-11)1+(-1)3/3+1

Answer 7

you have no y varible in the formula

Answer 8

dear @kninja99 now learn it carefully.
find the point P(x,y)... to find x .u have the formulas as above and to find y, use formula y1k2+y2k1/k1+k2 this will be the y coordinate... and same way x-coordinate...just put the values of x1 x2 in both the formulas of the coordinates.....

Answer 9

so first you do it where u use the x1 and x2 then change it to useing y1 y2? so its to seperate things to solve for the cordinate points right

Answer 10

yes...to solve for P(x,y) ...if u are going to find x...use x1 and x2 corrdinates and if u are going to find y of point P ,then use y1 and y2

Answer 11

ok ill solve it now

Answer 12

i got (8,4)

Answer 13

@waleed_imtiaz

Answer 14

yes thats absolutely right..so this will be point P(8,4)

Answer 15

thank you sooooo much for your help

Answer 16

my pleasure dear..keep it up
