Need as soon as possible, mainly need 30c answered though, I have the other two!!

Write an equation for each line in point-slope form and then convert it to standard form.

30a) write an equation of the line parallel to x+2y=6 through (8,3)

30b) write an equation of the line perpendicular to x+2y=6 through (8,3)

30c) Graph the three lines on the same coordinate plane.
