1 in 8 ramp means: for every 8 units horizontal, there will be a rise of 1 unit.
Example: 8 feet of horizontal distance will slope upwards to a finish height of 1 foot.
or
1 meter of horizontal distance will slope upwards to a finish height of 125 mm.
In both examples height/horizontal length = 1/8 or 125/1000 = 1 in 8.

If you mean: y = 12x+1 then it has a positive slope of 12 and a y intercept of 1
The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.The slope of the perpendicular is the negative reciprocal of the slope of a line. In this case, - (1 / -1) = 1.
p (2,-1) and slope 3
If you mean points of (-2, -1) and (3, 5) then the slope is 6/5
If you mean points of (6, -2) and (-3, 7) then the slope works out as -1
