Answer:
Slope of line =
Slope of parallel line =
Slope of perpendicular line = (-2)
Step-by-step explanation:
Slope of a line passing through two points and is,
Therefore, equation of a line passing through points (1, -3) and (-1, -4) will be,
If the slope of a line parallel to the given line is ,
Then by the property of parallel lines,
Therefore, slope of the parallel line will be .
Property of perpendicular lines,
Therefore, slope of the perpendicular line will be (-2).
