Question

Find the equation of the line that is perpendicular to this line and passes through the point(0,0) and is perpendicular to the line shown above?

Answer 1

There is not a line shown above, but to solve this you would need the opposite and reciprocal slope and a y-intercept of 0. 

To get an opposite and reciprocal slope, you simply flip the fraction and change the sign. So, if the original slope was 3/4, the new one would be -4/3.
