Question 631304
Find the slope of a line perpendicular to the line passing through the given two points.
(0, 0) and (9, -2)
**
slope of a line passing through the given two points, (0, 0) and (9, -2)
=∆y/∆x=(-2-0)/(9-0)=-2/9
..
slope of a line perpendicular to the line above.
=9/2 (negative reciprocal of slope of line above)
