write the slopeintercept equation for the line that passes through (8,11) and is perpendicular to 2x7y=14

Lines perpendicular to:
2x7y=14
would have the form:
7x+2y=k
where k is a constant to be determined using the point (8,11).
Substitute x=8, y=11, we get
7(8)+2(11)=k
=>
k=34
The line is therefore
7x+2y=34
