For any two perpendicular lines (save a vertical and a horizontal one), the product of their slopes is always -1. For two perpendicular lines with one having a slope of -2, the other will have a slope equal to -1 divided by -2, which equals 1/2.
-- The slope of the graph of [ 4x + y = 2 ] is -4.-- The slopes of perpendicular lines are negative reciprocals.-- The slope of any line perpendicular to [ 4x + y = 2 ] is 1/4 .
The shortest distance between two paralle lines is the length of the line that is perpendicular to both line and intersects both.
For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )

y=-2 is parallel to the x-axis and perpendicular to the y-axis.
intersecting lines are alike because perpendicular lines have to intersect to be perpendicular. 2: They are the same because they touch another line so they are the same.
The shortest distance between two paralle lines is the length of the line that is perpendicular to both line and intersects both.
The slope of the perpendicular is -(1/2) .
Perpendicular lines intersect at right angles. (90°) Therefore, by the definition of perpendicularity, two perpendicular lines must intersect.
Put 2 lines on the perpendicular sides and put 1 line for the parallel sides
For the line 2x + y = 8 , the slope equals ( -2 ) so the required slope of the line which is perpendicular to it is equal to (+1/2 )
