Question 603736
Line 1: 3x - y = -2
3x + 2 = y
the slope of this line is 3


Line 2: x - 3y = -9
x + 9 = 3y
(divide all by 3)
1/3 x + 3 = y
the slope of this line is 1/3


because the two slopes aren't same, they are not parallel
because slope 1 * slope 2 not equal with -1, they are not perpendicular


so, the two lines are neither parallel nor perpendicular
