-- 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 slope is a negative number.
Slope of perpendicular line is the negative reciprocal. So it is -1/4
Points: (-10, -4) and (-1, 2) Slope: 2/3
Slope equals (y2 - y1) / (x2 - x1). In this case, the points are (-2, -4) and (1, 2), so the slope is (2 - (-4)) / (1 - (-2)) = (2+4)/(1+2) = 6/3 = 2.
If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.
Make the slope a negative reciprocal. That means that you change the sign ( a positive number becomes negative or a negative number becomes a positive ). You also flip the slope as though it were a fraction (4/5 becomes 5/4. And 2/1 becomes 1/2). So if the slope was 3x it would now be -1/3x.

Points: (-10, -4) and (-1, 2) Slope: 2/3
The slope is -1 - 4 / -2 - 2 = -5/ -4 = 5/4
Points: (0, -1) and (-2, -4)Slope: 3/2
Points: (3, 2) and (-1, -4) Slope: (2--4)/(3--1) = 3/2 or 1.5
