Step-by-step explanation:
Answer:
B. (x+1)^2 + (y-7)^2=196
Step-by-step explanation:
The equation is (x-h)^2 + (y-k)^2=r^2
h=-1,k=7 and r=14
(x-(-1))^2 + (y-7)^2= 14^2
(x+1)^2 + (y-7)^2 = 196
Answer: 
Step-by-step explanation:
By definition, the slope of the line is described as "Rate of change".
You need to use the following formula to calcualte the slope of the line;

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).
Then, you can say that:

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

Finally, you must evaluate in order to find the slope of this line. You get that this is:
