Hi
slope of a line that passing through points (5, -8) and (3, -3)
Using the point-slope formula, {{{m =(y[2] - y[1])/(x[2] - x[1])}}}
(5, -8) and 
(3, -3)   m = [-8-(-3)] / (5-3)  = -5 /2 
 With m = -(5/2) the line is oblique, slanting to the left
Note: as y increases/decreases by 5, x value changes by 2 in the other direction
example shown of y = -(5/2)x -3
