Answer:
y=4x-16
Explanation:
We want to find the equation of the line in the form y=mx+c, where m is the slope and c is the y-intercept.
If the lines are parallel, their slopes will be the same. The slope of y=4x+1 is 4.
Our equation is now y=4x+c. Sub in point P to get c:
4=4(5)+c
4=20+c
c=-16
Therefore our equation is y=4x-16
