Answer:
-1/4
Explanation:
The slopes of perpendicular lines are reciprocals of each other,
meaning if the slope of one line is 4 then its perpendicular lines slope is -1/4.
Thus,
its slope is -1/4.
Hope this helps :)
Perpendicular lines have slopes that multiply to -1
m * 4 = -1
Divide by 4
m = -1/4
The slope of a line that is perpendicular to a line that has a slope of 4 is -1/4
