A grid map marks the plot of Harold's garden in meters. The coordinates of the quadritateral-shaped property are \( \mathrm{G}(-8,3), \mathrm{A}(4,8), \mathrm{R}(10,0) \), and \( \mathrm{D}(-2,-5) \). He wants to build a short fence around the garden The perimeter of his garden is

\( (-9,-1) \) and \( (12,14) \) Slope \( = \)

The midpoint between two points is \( \{1,5\rangle \). One of those points is \( \{8,3\rangle \), find the other.

7. A village with an actual area of \( 1 \mathrm{~km}^{2} \) is represented by an area of \( 4 \mathrm{~cm}^{2} \) on a map. (a) Express the scale of this map in the form \( 1: n \), where \( n \) is an integer.

coordinate grid below. Find the coordinates of a fourth point o that the four points form the vertice of a rectangle.

Draw a graph of the line that contains the given point and has the given slope. \( (-5,0) ; m=\frac{1}{5} \)
