Question

if the points (7,-2) (5,1) and (3,p) are collinear then find the value of p ​

Answer 1

Answer:

Point A(7,−2),B(5,1) and C(3,k) are collinear if

Slope of AB= Slope of BC

1-(-2)/5 - 7 = p - 1/3-5

3 /-2 = p- 1 /-2

p -1 = 3

p = 3+1

p = 4 ans.

Answer 2

Slope of AB= Slope of BC

1-(-2)/5 - 7 = p - 1/3-5

3 /-2 = p- 1 /-2

p -1 = 3

p = 3+1

ans:  p = 4
