Answer:
-2/5
Explanation:
y = 5/2x - 1
m = 5/2
The equation of a perpendicular line to y = 5/2x - 1 must have a slope that is the negative reciprocal of the original slope.
So, the line perpendicular is -2/5
Answer
Further explanation
Perpendicular lines have slopes that are negative inverses of one another.
That means we take the slope and turn it over:
5/2 = 2/5
Now make it a negative: -2/5
CONCLUSION:
The slope is -2/5.
