Answer:
-4/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-5)/(9-2)
m=-4/7
The distance of DC=HG,4.47; distance of CB=GF, 2.23; distance of BA=FE, 2.23; distance of AD=EH, 3.16
Answer:All sides are congruent so the shapes are congruent
Hope this helps :)
A = side^2 * (2 + 2sqrt2))
A = 4^2 * (2 + 2sqrt2))
A = 77.25 cm^2

Step-by-step explanation:
Answer: ![(-\infty, -4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%5D)
Curved parenthesis at negative infinity
Square bracket at -4
====================================================
Work Shown:

The last inequality shown above is the same as saying 
Converting this to interval notation leads to the final answer of ![(-\infty , -4]](https://tex.z-dn.net/?f=%28-%5Cinfty%20%2C%20-4%5D)
Note the use of a square bracket at -4 to include this endpoint. We can never include either infinity, so we always use a parenthesis for either infinity.
