X Expert Source Grace Imson MA Math Instructor City College of San Francisco Expert Interview. To be perpendicular they only need to have opposite reciprocal slope. Y y 1 14x x 1 And now put in the point 72.
M 14 14.
Before you calculate the equation of the perpendicular line you will need to find the slope of the line that crosses the two points. The negative reciprocal of that slope is. By looking at the coefficient in front of x we know that the slope of this line has a value of 2. This simply means if the original slope is m the reciprocal is 1m.
