please help me to solve this problem

Answer:
y = 3x -5
Explanation:
Since it's parallel, it will have the same slope: 3.
So you'll have y = 3x + a, and we need to find a.
Plug in the values for the point we are given:
7 = 3(4) + a
7 = 12 + a
a = -5
Answer:
y=3x-5
Step-by-step explanation:
y=3x+6
since the line is parallel, the slope will be the same (but y int is still unsolved)
so plug in x,y from (4,7) in y=mx+b or y-y1=m(x-x1)
i used y=mx+b
7=3(4)+b
7=12+b
b=(-5)
so the final answer is y=3x-5
