5 is the answer of this question

Step-by-step explanation:

hope this will help you

Answer 2

Answer:

k=0

Step-by-step explanation:

Points A(2,3),B(4,k) and C(6,−3) are collinear.

Area of triangle having vertices A, B and C=0

Area of a triangle =

Area of given ΔABC=0

⇒

[2(k−(−3))+4(−3−3)+6(3−k))]=0

⇒2k+6−24+18−6k=0

⇒−4k=0

or k=0

The value of k is zero.
