Hi

line j is perpendicular to line k

slope of line j = 5/2

slope of line k = -2/5

Note: slopes of perpendicular lines are negative reciprocals of one another

that is: 5/2*-2/5 = -1

The letter used for slope is m.
If the slope of a given line is m, then
any line perpendicular to this line will have
a slope equal to +-1%2Fm+
given:
+m+=+5%2F2+
slope of perpendicular line =
+-2%2F5+
