How do you find the slope of a line perpendicular to the line to the line through the points (7,-10) and (6,-1)?
The perpendicular slope would be
Let's begin by finding the slope of the line through the two points,
Slope is The change in
and can be found using the equation
For the points given the coordinates are
Plug in the values and solve for slope
The line perpendicular to this line would have a slope that is the inverse of this line. Both in sign and reciprocal.
