Answer:
y=4x-7
Step-by-step explanation:
Add 12x to both sides to get 3y=12x-9
Divide by 3 to get y=4x-3
If the line is parallel, the slope is still 4x. So it is y=4x+n.
If in the coordinate point, x=2, and y=1, then the equation is now:
1=(4*2)+n, or 1=8+n
Subtract 8 from both sides to get n=-7
So, the equation is y=4x-7
