Answer:
y=2x-7
Explanation:
y=mx+b
Since the lines are parallels, that means that their slopes are the same, so you can use the slope which is 2.
Then you can substitute the points in to find the b.
1=2(4)+b
1=8+b
-7=b
You can substitute this into the equation and get, y=2x-7.
Please correct me if I am wrong. I hope you understand!
