Answer:
Yes, it does. 
Step-by-step explanation:
The equation y = 4x is the same as saying:
"The y coordinate is 4 times as much as the x coordinate"
So, with the coordinate set of (2, 8):
y = 4x
8 = 4 * 2
This is correct, meaning the coordinate does fit the equation.
Hope this helps!

Answer:
The graph will be  2 units away from the origin on positive
 2 units away from the origin on positive  and three units upward from the origin towards
 and three units upward from the origin towards  .
.
Step-by-step explanation:
Here is a graph attached with it.
To graph  we know that positive
 we know that positive  is a
 is a  shaped from the origin.
 shaped from the origin.
Key points:
- To move rightward there must be a negative inside the parentheses.
- And to move upward we must have positive  . .
If we have to move towards  then we must have negative inside it.
 then we must have negative inside it.
And if we have to move upward in  positive we must have positive constant value.
 positive we must have positive constant value.
So the graph will be three units upward and two units rightward with a V-shaped ray.
