Question

and has diameter 10 v2 Units.
12. (i) Show that the points (4,3), (2,0) and (-4, - 9) are collinear.
(ii) Show that the points (-1, -1), (2, 3) and (8, 11) are collinear​

Answer 1

Step-by-step explanation:

if Slope of AB is equal to slope of BC then A, B, Care collinear

A=(4,3),

B=(2,0)

and

C=(-4, - 9)

slope of AB = difference of y coordinates/ difference of X coordinates

=(3-0)/(4-2)

=3/2------->I

slope of BC = difference of y coordinates/ difference of

X coordinates

==(-9-0)/(-4-2)

=-9/-6

=3/2----->II

from I and II

A, B, C, are collinear
