Question

Use slopes determine three points are collinear A (-2,3),B(8,-5) and C(5,4)

Answer 1

Answer:

NO THEY ARE NOT COLLINEAR

Step-by-step explanation:

FOR THREE POINTS TO BE COLLINEAR THEY MUST HAVE A SAME SLOPE

FIRST WE WILL FIND THE SLOPE USING POINT A AND B

SLOPE OF A AND B = -5-3/8+2= -4/5

THEN WE WILL FIND THE SLOPE USING POINT B AND C

SLOPE OF B AND C = 4+5/5-8= -3

IT IS CLEAR THAT THE TWO SLOPES ARE NOT EQUAL THEREFORE THE GIVEN THREE POINTS ARE NOT COLLINEAR.
