A, B and C are three points such thatAB→ = 3a + 4bAC→ = 15a + 20b(a) Prove that A, B and C lie on a straight line
Question
Solution 1
To prove that points A, B, and C lie on a straight line, we need to show that the vectors AB and AC are collinear. This means that one vector is a scalar multiple of the other.
Given vectors AB→ = 3a + 4b and AC→ = 15a + 20b, we can see that AC is a scalar multiple of AB.
Divide AC by AB:
