Write an eqaution of the liine that passes through the point at (4, 4) and is perpendicular to the line whose equation is 2x + y = 7

now i did

x | 2x + y = 7 | y
-----------------------
0 | 2(0) + y =7 | 7
1 | 2(1) + y =7 | 5
2 | 2(2) + y =7 | 3
3 | 2(3) + y =7 | 1

so i ploted the the points:
0, 7
1, 5
2, 3
3, 1

now can you help me out with the equation writing?

x-2y=?
4-4(4)=?
