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!
Answer:

Step-by-step explanation:
The constraints are
The red line represents the function

At 

At 

Two points are 
The blue line represents the function

at 

at 

Two points are 
The other two constraints are
,
. So, the point has to be in the first quadrant
From the graph it can be seen there are two points where the function will be maximum let us check them.




So, the maximum value of the function is
.
