If you mean: (0, 0) and (6, 7) then the slope works out as 7/6
It is 2.
If you mean: (0, 0) and (6, 7) then the slope works out as 7/6
If the points are (0, 0) and (2, 4) then the slope works out as 2
If you mean: (0, 0) and (2, 4) then the slope works out as 2
Of course it can and it does: it is the x-axis.
Points: (8, 2) and (0, 0) Slope: 1/4 or 0.25 Equation: y = 0.25x
If the points are (1,5) and (0,0) y = 5x
If you mean points (6, 2) and (0, 0) then the slope is 1/3 and the equation is y = 1/3x
Points: (1, 9) and (0, 0) Slope: 9 Equation: y = 9x
If you mean points (7, 2) and (0, 0) then the slope is 2/7 and equation is y = 2/7x
If you mean points of: (2, -8) and (0, 0) then the slope is -4 and equation is y = -4x
Points: (8, 2) and (0, 0) Slope: 1/4 or 0.25 Equation: y = 0.25x
