Question

A vector starts at point (-8, -1) and ends at point (6,-9) what is the horizontal component of the vector?

Answer 1

$\begin{gathered} \text{Start (-8,-1)} \\ \text{End (6,-9)} \\ V=(6-(-8))i+(-9-(-1))j \\ V=(6+8)i+(-9+1)j \\ V=14i+-8j \\ 14i\text{ = horizontal component of the vector},\text{ hence} \\ The\text{ }horizontal\text{ component of the vector is 14} \\ \end{gathered}$
