Since the other line's equation is in slope-intercept format and the perpendicular line would have an inverse slope, that slope would be -3/5

Except I was talking inverse of slope (change in y divided by change of x), not inverse reciprocal. Imagine a line passing thru (0,0) at an angle of 45 degrees to the x-axis. For every change of 1 in x, there is a corresponding change of 1 in y for a slope of 1. Now think of a line perpendicular to the first, also passing thru (0,0) at an angle of -45 degrees to the x axis. On that line, for every increase of x by 1, y decreases by 1, so the slope in that case is -1.

Good logic, but inverse reciprocal of 3/5 is (-5/3) !!!01/04/19
