Answer 1

Answer #1

Slope Of line is given by : (y2-y1) /(x2-x1)

Therfore slow of line is =(5-3)/(1-2) = 2/(-1) = - 2

Slope = - 1

Since parallel lines have equal slope

Therfore slope of parallel line =-1

Since slope of perpendicular lines are negative reciprocal of each other

Therefore slope of perpendicular line = 1
