Slope = y2 - y1/x2 - x1
= -3 - (-1)/8 - (-2)
= -3 + 1/ 8 + 2
= -2/ 6
= - 1/3

hope this helps :)

Slope is rise/run so you need the difference between each x and y
-2 and 8 have 10 units between them
-1 and -3 have 2 units
y is the rise, and x is the run
so your slope is 2/10 or 1/5
it is negative because the line is going downward
final answer is -1/5

A 70-meter path surrounds a rectangular garden. The width of the garden is two-thirds its length. Find the length and the width.

$width=\frac{2}{3}length\\\\
70=2width+2length\\\\
70=2length+2(\frac{2}{3}length)\\\\
70=2length+\frac{4}{3}length\\\\
70=\frac{10}{3}length\ \ | divide\ by\ \frac{10}{3}\\\\
70*\frac{3}{10}=length\\\\
length=21m\\\\
width=\frac{2}{3}*21=14m
