Answer 1

Solution:

Given the coordinate grid below:

The starting point is at (-5.5, 2), and the finishing point at (2, -5.5).

To determine the quadrants in which the starting and finishing points are located, we have

This implies that

$\begin{gathered} starting\text{ point}\Rightarrow\text{ Quadrant Q} \\ finishing\text{ point}\Rightarrow\text{ quadrant S} \end{gathered}$

Explanation:

The starting point has its coordinates to be (-5.5, 2). This implies that the x value is on the negative axis and its y value is on the positive axis. Hence, we have the location to be in quadrant Q.

The finishing point has its coordinate to be (2, -5.5). This implies that the x value is on the positive x-axis and the y value on the negative y-axis. hence, we have the location to be in quadrant S.
