Answer:
y = -1/4x + 7
Step-by-step explanation:
Plug in the point and slope into y = mx + b, and solve for b:
y = mx + b
8 = -1/4(-4) + b
8 = 1 + b
7 = b
Plug in the slope and b into y = mx + b:
y = mx + b
y = -1/4x + 7
So, the equation of the line is y = -1/4x + 7

Answer:

Step-by-step explanation:
The domain of a function is all of the values that  can be under that specific function. In this case, we're asking what values of
 can be under that specific function. In this case, we're asking what values of  allow
 allow  to exist.
 to exist. 
In order for square roots to exist, the quantity under the square root must be greater than or equal to  , because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for
, because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for  :
:

Solving this inequality, we get:

 (Subtract
 (Subtract  from both sides of the inequality to isolate
 from both sides of the inequality to isolate  )
)
 (Multiply both sides of the inequality by
 (Multiply both sides of the inequality by  to get rid of
 to get rid of  's coefficient)
's coefficient)
Hope this helps!
