Answer:
Step-by-step explanation:
First off, what's the slope of "r" anyway,
.
low and behold, since "r" is in slope-intercept form, notice, it has a slope of -1/2.
now, any line perpendicular to "r", will have a
negative reciprocal slope to it, that is,
so we're really looking for a line whose slope is 2, and runs through 4,-3,
