Points: (-12, -17) and (21, 5) Slope: 2/3
Points: (2, 1) and (5, 3) Slope: 2/3
If you mean points of (2, 1) and (0, -5) then the slope of the line is 3
2
If you mean points of: (-2, 1) and (3, 5) then the slope works out as 4/5
If you mean points of (-1, 9) and (5, 21) then the slope of the line works out as 2
If you mean points of (-1, 9) and (5, 21) then the slope works out as 2
If the points are (2, 1) and (-6, -4) then the slope works out as 5/8

The slope of a line and the perpendicular to that line, when multiplied together, give -1. So, if the first line has a slope of 1/21, the second has a slope of -21.
Points: (21, 10) and (-19, 0) Slope: 1/4
Points: (14, 6) (21, 9) (7, 3) Slope of the line: 3/7 Equation of the line: 7y = 3x and it has no y intercept
