The slope of two lines are perpendicular only if their slopes multiplied together equal -1 (m1*m2 = -1). So if a line has a slope of -3 then a line perpendicular to this one has a slope of -1/-3 or 1/3.
Points: (-2, 3) and (1, 1) Slope: -2/3
Points: (-1, 2) and (3, 3) Slope: 2-3/-1-3 = 1/4
Points: (-1, 2) and (4, 3) Slope: 1/5
Points: (-3, -1) and (3, -2) Slope: -1/6
Points: )1, 1) and (3, 3) Slope: 1
If you mean points of (1, 5) and (-1, -1) then the slope works out as 3

Points: (-2, 3) and (1, 1) Slope: -2/3
Slope = (1 - 4)/(3 - 1) = -3/2 = -1.5
If you mean points of (3, 3) and (-3, -1) then the slope works out as 2/3
Points: (-3, -1) and (3, -2) Slope: -1/6
Points: (1, 3) and (3, -2) Slope: -5/2 or -2.5
Points: (1, 7) and (-3, 2) Slope: 5/4 or 1.25
Points: (-1, 2) and (3, -1) Slope of line: -3/4
