Answer:
Y=-1; y+1=0(x+4)
Step-by-step explanation:
Point slope form: y-y1=m(x-x1)
A horizontal line has a slope of "0" therefore our "m" value is 0
So
y+1=0(x+4)
Y+1=0x+0
y=-1
Hope this helps!
In case you're not already aware, the expression 
is called the "difference quotient" and represents the average rate of change of a function 
over an interval ![[x,x+h]](https://tex.z-dn.net/?f=%5Bx%2Cx%2Bh%5D)
.
For the function 
, by substituting 
we get
Then the difference quotient is
where the last equality holds as long as 
.

m^2 + 9 = 0
m = ± 3i
yH = C1 cos 3t + C2 sin 3t
yP = C3 t sin 3t + C4 t cos 3t

To estimate 2641 x 9 is that you round each number. so it would be 2641 to 2640 and the 9 would round to 10. 2640 x 10
