The browser used by this site for posting questions is pretty pathetic since it permits no punctuation. In this case it is not possible to tell whether the second point is meant to be (3, 10) or (31, 0).
Do you mean: (-4, -11) and (-18, -19) Then the slope is: (-11--19)/(-4--18) = 4/7
If you mean: (0, 11) then y = x+11
-24
36 = 729 and 310 = 5904936 = 729 and 310 = 5904936 = 729 and 310 = 5904936 = 729 and 310 = 59049
310
Points: (-11, -17) and (-14, -19) Slope: 2/3
Do you mean: (-4, -11) and (-18, -19) Then the slope is: (-11--19)/(-4--18) = 4/7
Points: (-1, -11) and (-6, -7) Slope: -4/5
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
It appears that the point has only one coordinate: 310. In two dimensional space, such as the coordinate (or Cartesian) plane, a point needs two coordinates.
If you mean y = 11x then the slope is 11
