The line perpendicular to a line with a slope of 1/5 has a slope of -5.
Points: (10, 1) and (5, 2)Slope: -1/5
4
the answer is - 1/5
Points: (1, -3) and (2, -5) Slope: -2
Endpoints: (-1, 1) and (1, 5) Slope: 2
Points: (1, -5) and (3, 5) Slope: 5
Points: (1, -5) and (3, 5) Slope: 5
The slope is 5.
1/5.
Points: (1, -1) and (5, -7)Slope: -3/2
slope=(2-1)/(3-5)=-1/2
