The slope of a line passing through two points with given x y coordinates can be found by dividing the (signed) difference between the two y coordinates by the (signed) difference between the two x coordinates, being careful to take the coordinates in the same order for each subtraction. In this instance, the slope is (-4 - 4)/(-1 - 3) = -8/-4 = 2.
Slope = (1 - 4)/(3 - 1) = -3/2 = -1.5
If: slope is 3 and point is (1, 4) Then: y = 3x+1
If you mean points of: (-1, 2) and (-4, -3) Then the slope works out as: 5/3
Points: (-1, 2) and (3, -1) Slope of line: -3/4
If you mean: (-4, 1) and (1, 4) Then the slope works out as: 3/5
Points: (4, 3) and (-3, -4) Slope: (-4-3)/(-3-4) = 1
Points: (-1, 2) and (4, 3) Slope: 1/5
Points: (3, 2) and (-1, -4) Slope: (2--4)/(3--1) = 3/2 or 1.5
Points: (1, 7) and (-3, 2) Slope: 5/4 or 1.25
Points: (-3, 4) and (1, -2) Slope: (4--2)/(-3-1) = -3/2 or -1.5
Points: (3, -4) and (-2, 1) Slope: -1 or -x
Points: (0, -1) and (-2, -4)Slope: 3/2
Points: (-3, 1) and (2, 4) Slope: (4-1)/(2- -3) = 3/5
Points: (3, 4) and (2, 1) Slope: 3
Points: (1, 14) and (3, 4) Slope: (4-14)/(3-1) = -5
If the points are: (4, 3) and (6, 1) then the slope works out as -1
The slope = (y2 - y1)/(x2 - x1) = (7 - 3)/(4 - 1) = 4/3
