If you mean h(4)
h(4)=(4)*2 -5(4)
=8-20
=-12
The answer will be-12
        
             
        
        
        
Answer:
y=3x+10
Step-by-step explanation:
First, put the equation into point-slope form.
y-y1=m(x-x1)
y-4=3(x+2)
Next, distribute 3 to (x+2) and simplify.
y-4=3x+6
y=3x+10
 
        
             
        
        
        
You have to make an equation that i forgot what was called but you just take 
x+y=10 and multiply it by -2 so the y’s can cancel out 
so you’ll end up with:
 -2x-2y= -20 
(+) x+2y=14
you’ll get : x = -6 
then you plug in -6 for x, solve for y and your coordinates will be 
(-6 , 10)
        
                    
             
        
        
        
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
By definition, if two lines are parallel then their slopes are equal.
We have the following line:

Thus, the slope is:
Then 
So, the line is of the form:

We substitute the point and find b:
and find b:

Thus, the equation is:
