the slope of the new equation must be the negative reciprocal of the slope
of the old one
slope of old = -5/3
slope of new = 5/3
The only choice you give that has a slope of 5/3 is the last one, so you know
for sure that the first 3 cannot be it.
All you have to do is make sure the given point satisfies the last equation,
since there is a possibility that none are correct.
So do that to make sure.
Which is the equation for the line perpendicular to y = -5/3x + 11 1/3 and containing P(-2,3) ?
a) y - 2 = -3/5(x - 3)
b) y = -5/3x + 4 1/3
c) y = -3/5x + 4 1/5***
d) y = 3/5x + 4 1/5
