An equation of a line perpendicular to y=23x−7 is

Question

An equation of a line perpendicular to  is

Answer 1

y=-(1/23)x + any constant

y=-x/23 + 10

Unless maybe the 23 was a typo that should have been written as y=(2/3)x -7 then a perpendicular

line would b y=-(3/2)x + 10

for a perpendicular line just change the sign of the x coefficient and flip it upside down, then add any constant.
