Mathematics 10 — Exercise 6.1 · Q9 (i)

Full question

Decide whether these vectors are parallel.

Step-by-step solution

1. Two nonzero vectors are parallel if the SAME scalar multiplies both components.

2. Use the horizontal components to find the possible scalar.

   $$\lambda =\frac{12}{6}$$

3. Reduce that quotient.

   $$\lambda =2$$

4. Check the vertical component using the same scalar.

   $$(2\times 1=2,2)$$

Answer

Parallel.
