The line is vertical and so the slope is undefined.
Points: (1, 2) and (3, 8) Slope: 3
The slope is -2/3.
Points: (1, -1) and (5, -7)Slope: -3/2
Points: (2, 5) and (-1, 5) Slope: 0 and so therefore it has no slope but is a straight line parallel to the x axis
Points: (-2, 3) and (1, 1) Slope: -2/3
The line is vertical and so the slope is undefined.
The slope is 1/2.
Points: (2, -2) and (8, 1)Slope: 1/2
which equation has a slope of -1/2 and a graph that passes through (-3,4)?
The slope is (6 - 1)/(1 - 2) = 5/(-1) = -5
The slope would be 2,6.
Another coordinate is needed to work out the slope.
-5/3
-3/4
Points: (1, 2) and (3, 8) Slope: 3
The slope is -2/3.
