-3/2
===========
The given line is 2x - 3y - 5 = 0.
To find the slope of a line that is perpendicular to this line, we need to find the slope of the given line and then take its negative reciprocal.
The slope-intercept form of a line is:
- y = mx + b, where m represents the slope
Rearranging the given equation in this form, we get:
And dividing by 3, we get:
So, the slope of the given line is 2/3.
To find the slope of a line perpendicular to this line, we take the negative reciprocal of 2/3, which is -3/2.
Therefore, the slope of a line perpendicular to the given line is -3/2.
