Question

the Slope of a line is 1 by 2 write the Slope of a line parallel to given line write the Slope of a line perpendicular to the given line​

Answer 1

slope of line parallel to given line is m1 = m2

so, slope of parallel line is 1 by 2

slope of line perpendicular to given line is m1.m2 = -1

so, slope of perpendicular line is -2
