First, find the gradient/slope:
Use slope formula:
m=(y2-y1)/(x2-x1)
 =(11-5)/(3-1)
 =6/2
 =3
Then use the line equation formula:
y=mx+c
You can substitute (1,5) if you like, also must substitute the slope as well!
5=3x1+c
c=2
Then find the full equation, which gives you the answer:
y=3x+2
        
             
        
        
        
A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
A function can be represented algebraically. For example, 3x+6 3 x + 6 .
A function can be represented numerically.
A function can be represented graphically.

Answer:
(9, 6)
Step-by-step explanation:
To find the midpoint of the endpoints, you need to find the average of the coordinates. 
5+13=18/2=9
1+11=12/2=6
So, the midpoint is (9,6)
