Question

show that ,A(-3,2) B(1,-2) & cg ,-10) are collinear. Dupoose ,​

Answer 1

Seems like your question is 'show that ,A(-3,2) B(1,-2) and C(9 ,-10) are collinear.

Answer:

Slope of the line made by any point must be same in all cases.

Slope of line through (-3, 2) and (1, - 2):

= (2 - 1)/(-3 -(-2) )

= - 1

Slope of line through (1, -2) and (9, -10):

= (9 - 1)/(-10 -(-2))

= 8/(-8)

= - 1

As the slope of the line made by these points is same, they are collinear.
