negative is the answer.
Is the vertical slope the reciprocal?
The vertical line has the opposite slope to the reciprocal. In this case, the slope of the first line is -2. The reciprocal of -2 is -1/2, so the reciprocal is 1/2
The slopes of the two perpendiculars are the reciprocals of each other. That is if the line is perpendicular to the line with a slope of m, the slope of the line is -1 / m. For example, the slope of a line y = (1/2) x + 3 1/2
was found to be the reciprocal of the value, as opposed to the vertical slope. That is, get one tilt value and turn it upside down. (This is not clear about the slope of the vertical line.)
