The line is vertical and so its slope is undefined. Some may argue that it is infinity.
The slope is zero.
The slope of the line that passes through the points (3,15) and (5,9), is -3; use the formula change in Y-axis/change in X-axis.
Points: (-2, 4) and (-6, 12) Slope: -2
y=mx+b

The slope of a line that passes through two points is (difference in y) / (difference in x).
Where are the points!
The slope is zero.
The slope is 2.
The slope is 1/2.
The slope of the line that passes through the points (3,15) and (5,9), is -3; use the formula change in Y-axis/change in X-axis.
Points: (2, 1) and (5, 3) Slope: 2/3
Points: (14, 5) and (20, 4) Slope: -1/6
The slope is -2/3.
Points: (0, 5) and (10, -15) Slope: -2
Points: (-2, 4) and (-6, 12) Slope: -2
Points: (3, 15) and (5, 9) Slope: -3
