Question

determine whether the points are collinear a(0,2) b(1,0.5) c(2,-3)​

Answer 1

Answer:

A(0,2), B(1,-0.5), C(2,-3)

Slope of AB =

1−0−0.5−2

= 1−2.5

=−2.5

Slope of BC = 2−1−3−(−0.5)

= 1−2.5

=−2.5

So, the slope of AB = slope of BC.

Point B lies on both the lines.

Hence, the given points are collinear.

Answer 2

Answer:

NO THESE ARE NOT COLLINEAR.

Step-by-step explanation:

IF THESE POINTS GIVES AREA EQUAL TO ZERO THEN THESE ARE COLLINEAR OTHERWISE NOT.

AREA =

1/2[0(0.5+3) +1(–3–2) +2(2–0.5)]

= 1/2[ 0–5+3]

= 1/2(–2)

= –1.

HENCE THESE ARE NOT COLLINEAR.
