First off, really sorry if i put this in the wrong thread, its my first time on this forum. These questions are from my university calculus book, but in the review section, and for that reason, i didn't put this in the calculus section of the forum.

Write equations of the lines through the given point (a) parallel to the given line and (b) perpendicular to the given line.

1. (-3, 2) x + y = 7

2. (-2/3, 7/8) 3x + 4y = 7

3. (-1, 0) y + 3 = 0

Thanks in advance!
