So, what's the slope of y = 2x - 4? well, is in slope-intercept form, thus
, so is 2.
now, a perpendicular line to that, will have a negative reciprocal slope to it, thus
so, that's its slope of that perpendicular line.
but we also know that it runs through (5,r) and (2,3), so that slope is equal to -1/2
