1)required line is parallel to x+3=0 and passes through (-6,-7)

equation of such line will be x=c. since it passes through (-6,-7)

-6=c or

x=-6

x+6=0

[NOTE: line x+k=0 is perpendicular to x axis so any line parallel to it must also be perpendicular to x axis and in the form x+k=0]

2) line perpendicular to y-4=0 will be in the form x=c.

since it passes through(-1,6)

we have -1=c

or c=-1

x=-1

x+1=0
