In general, any point on the plane can be identified by an ordered pair (x,y). To find x, move along the x-axis until you are below/above the point. To find y, move along the y-axis until you are to the right/left of the point.
13) Therefore, in our case, the coordinates of the points are
[tex]\begin{gathered} (-1,1), \\ (-1.5,2)\to\text{approximate} \\ (-2,3) \end{gathered}[/tex]
