Question

show that the points p (1, 1 )lies on the line segment joining the points A (3, - 2) and B( - 1, 4)​

Answer 1

yes (1,1) lies on AB line segment

Step-by-step explanation:

(1,1) (3,-2) (-1,4)

x1 y1. x2 y2. x3 y3

centroid formule= x1+x2+x3. y1+y2+y3

( ------------- , --------------)

3. 3

= 1+3-1. 1-2+4

(-------- -------)

1. 3. 3

= 0+3. -1+4

( ------ -----)

3. 3.

= 3. 3

( ---- ----)

3. 3.

=(1,1)

therefore 1,1 is lying in the line segment AB
