Answer:
The equation of the line is 
2y=x+8 
Step-by-step explanation:
This is a straight line graph.
And general equation of a straight is given by
y=mx+c
Where m is slope 
c is the intercept on y axis at x=0
So at y=0, x=8. This is from the graph.
And inserting this value of y and x into the straight line equation
y=mx+c
0=-8m+c
Therefore, c=8m. Equation 1
Taking another point on the graph 
at=0, y=4
Also, inserting this value of y and x into the straight line equation
4=0×x+c
4=0+c
Therefore, c=4.
Therefore the intercept is 4
From equation 1
 c=8m c=4
Then m=c/8
m=4/8
m=1/2
Then the equations of then line is
y=mx+c
y=(1/2)x+4
Multiply through by 2
2y=x+8
The equation of the line is 
2y=x+8 
 
        
             
        
        
        
Answer:
v= -1 (BRAINLIEST PLEASE)
Step-by-step explanation:
|v+8| -5=2
Add 5 to each side
|v+8| -5=2
       +5= +5
Now you have |v+8|= 7
So what plus 8 equals 7?
-1
so now you have |-1+8| which is 7
so v= -1
 
        
             
        
        
        
Answer:
The relation  is explained below.
 is explained below.
Step-by-step explanation:
P(x, y) is a point on the circle. Q is the origin. Join PQ.
PQ is the radius.
Therefore, PQ = r
Draw PS perpendicular to the x-axis.
Now, ΔPQS is a right triangle.
By Pythagoros theorem,
