To find the slope of two given points...
slope (m) = y2 - y1/ x2 - x1
So that means the y coordinate of the second point minus the y coordinate of the first point, over, the x coordinate of the second point minus the x coordinate of the first point
In this case m = (-2) - (-5) / (-8) - (0)
m = 3 / -8
The slope is -3/8
Hope this helps :)
