Lines that are perpendicular have slopes that are the negative reciprocal of each other.
1) For the given line: y = -3x + 4 The slope here is -3.
The slope of the perpendicular line is -(1/-3) = 1/3
2) Parallel lines have slopes that are equal. For the given line -4x + 8 = 11
Rewrite this as: x = -3/4
This is a vertical line (parallel to the y-axis). Vertical lines have undefined slopes, so any line that is parallel to this one is also vertical and, therefore, will have an undefined slope.
