Question

Prove that the points (4 -5), (1, 1) and (-2, 7) are collinear

Answer 1

Step-by-step explanation:

By slope formula,

= y2-y1/x2-x1

Therefore,

== 1-(-5)/1-4

== 6/-3

== -2 ..... equation (1)

Now,

==7-1/-2-1

== 6/-3

== -2 ...... equation (2)

From equation 1 and 2 ,

slope of both are equal....

Therefore , it is proved that given points are collinear
