If m = dy/dx then the slope of a line perpendicular to line is
M = -1/m = -1/(2/3) = -3/2

the slope of a line that is perpendicular to the original slope is always the recipricoal of it
in this case the answer is negative three - halves

-3/2 its the opposite of 2/3. 2/3 and 2/3 run parallel and 2/3 and -3/2 are opposite lines and are perpendicular. Its a guarantee answer i don't know if the other people went to school.
Rise over run. count 2 up and 3 positive. thats your first position. next your answer is count 3 up and negative 2 to the left and you have your answer which is perpendicular.

When lines are perpindicular, their slopes are negative recipricals of each other.
the slope you are looking for is -1/(2/3)=-3/2
negative three-halves is correct.

-3/2.
Just flip the fraction over, and change the sign.
