Step-by-step explanation:
Answer:
y-6=4(x+1) or y=4x+10
Step-by-step explanation:
Point: (-1,6)
m=4
Slope-point form is y-y1=m(x-x1)
y1=6
x1=-1
Now, plug it in!
y-6=4(x-(-1)) which is y-6=4(x+1)
Of course, if you want you could always simplify it down to y=4x+10 if you wanted to
Hope this helps!

The given function is
f(x) = |x|
Moving 4 units to right means, subtracting the number from x. So moving |x| 4 units to right will give:
f(x) = |x-4|
Moving 2 units up means addition of a number to the function. So moving 2 units up will give:
f(x) = |x-4| + 2
Thus, the correct answer to the question is option B
Okay so...
There are 21 groups of 3.
21 x 3 = 63.
63 people are in the room.
