Answer:
Domain: ![(-\infty , +\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%20%2C%20%2B%5Cinfty%29)
Range: ![[-2,+\infty)](https://tex.z-dn.net/?f=%5B-2%2C%2B%5Cinfty%29)
Step-by-step explanation:
<u>Domain And Range Of A Function</u>
Let y=f(x) a real function. We call the domain of f to every possible value x can take that produces one real value for y. The range of f, is the set of all those values y can take when we take every possible element from the domain.
In the image, we can see the graph of a function who takes values of x without restriction, if x was greater than the maximum value shown in the graph, f(x) will take greater values also. The same happens if x was smaller than the minimum value shown in the graph. We can conclude the domain of x is ![(-\-\infty , +\infty)](https://tex.z-dn.net/?f=%28-%5C-%5Cinfty%20%2C%20%2B%5Cinfty%29)
We can also see the values of y come from
, then reach a minimum value of -2, and then increases without limits to
. This means the range is ![[-2,\infty)](https://tex.z-dn.net/?f=%5B-2%2C%5Cinfty%29)

Answer:
y-6=-3(x+6)
Step-by-step explanation:
Find the slope first, using the slope formula.
y2-y1/x2-x1
-9-6/-1--6 = -15/5
Slope is -3
Put it into point-slope form using one of the coordinates.
y-y1=m(x-x1)
y-6=-3(x+6)
The answer is 231/50
