Question

A( -5, 1) B(1, - 1) ad C( x, -2) . IF A, B, C are collinear, find x

Answer 1

Answer:

(i) Infinite number so line can be drawn to pass through a given point.

(ii) Only one line can be drawn to pass through two given points.

(iii) Two lines at the most can intersect at one point only.

(iv) AB,BC,AC

Answer 2

Step-by-step explanation:

according to question

distance of ab=bc

√(-5-1)²+(1+1)²=√(x-1)²+(-2+1)

squareing both sides

(-6)²+2²=(x-1)²+(-1)²

36+4=x²-2x+1+1

40-2=x²-2x

x²-2x-38=0

now u can solve this quartric equation
