Idk how to do this! :(
Write an equation of the line that passes through the given point and is perpendicular to the given line (1,1), y=3x+2

Math 
John,
For a line to be perpendicular to another line you need to use m in the linear equation of y=mx+b and find the opposite and reciprocal of that number. In this case m is 3 so the opposite of 3 is 3 and the reciprocal is just flipping the fraction of 3/1 so it is now 1/3. Now to find it going through a certain point you just take that 1/3 and subtract it from 1 and you will get 2/3. So the answer is y=1/32/3
