Answer:
The given point A (6,13) lies on the equation.  True
The given point  B(21,33) lies on the equation.  True
The given point  C (99, 137) lies on the equation.  True
Step-by-step explanation:
Here, the given equation is : 
Now,check the given equation for the given points.
1)  A (6,13)
Substitute x = 6 in the given equation

⇒ y= 13
Hence, the given point A (6,13) lies on the equation.
2)  B  (21,33)
Substitute x = 21 in the given equation

⇒ y  = 33
Hence, the given point  B(21,33) lies on the equation.
3)  C (99, 137)
Substitute x = 99 in the given equation

⇒ y  = 137
Hence, the given point  C (99, 137) lies on the equation.
