Question

Line 1 contains the points (6 1) and (6 50 write equation for line 2 that is perpindicular to line 1 and passes through the point (14 17). write an equation for line 3 that is parallel to line 1 and passes through (-4 9)

Answer 1

Perpendicular: 
(50-1)/6-6= slope=undefined= vertical line 
y-17=0(x-14)
y-17=0
y=17

Parallel: 
since line 1 is vertical we need another vertical line in order for them to be parallel so the line is x=- 4
