If two lines are perpendicular, their slopes are negative reciprocals of each other.
The slope of the line that goes through the points (2, 3) and (3, 2) can be found using the slope formula:
slope = (change in y) / (change in x)
slope = (2 - 3) / (3 - 2)
slope = -1
The slope of the other line is the negative reciprocal of the slope of the line that goes through the points (2, 3) and (3, 2), so it is:
slope = -1/-1
slope = 1
Therefore, the slope of the other line is 1.
