Question

If (2,4),(1,2) and(x-6) are collinear then the value of x is​

Answer 1

Answer:

x = -3

Step-by-step explanation:

using

y2 - y1 / x2 - x1 = y - y1 / x - x1

from (2,4) and (1,2) form equation

2-4/1-2 = y - 4 / x - 2

-2x +4 = - y +4

2x - y = 0

put (x,-6)

2x - (-6) = 0

2x = -6

x = -3
