10 4/7
Step-by-step i used photo math
Step-by-step explanation:
To transform a function vertically, add 3 to the constant.

So the function is

Graph the function in desmos to show the translation vertically if you want proof
Y+4x =7
Or y = -4x + 7
On comparing with point slope form
y = mx+c
We get m = -4 = slope of given line
As the required line is parallel to given line its slope is equal to -4
