(0, 0) and (-2 -2)
-2-0 divided by -2-0 which gives a slope of 1
.5 (y2-y1/x2-x1)
The slope is zero.
2
y = 0. You can get this from the slope-intercept equation of the line.
Points: (0, 0) and (4, 1) Slope: 1/4
y - 2 = 0
y - 2 = 0
y - 2 = 0
If you mean: (0, 0) and (2, 4) then the slope works out as 2
No slope is undefined i.e. a vertical line slope of 0 is a horizontal line... i believe...
Points: (0, 0) and (4, 1) Slope: 1/4
The slope is 1/2.
