Question

wats the slope (0,-1),(2,3)

Answer 1

Use the slope formula, the slope of the line through points (x1, y1) and (x2, y2) is
(y2 - y1)/(x2 - x1).
It doesn't make a difference which point you call (x1, y1) and which you call (x2, y2).
In your case,
slope = (-1 - 3)/(0 - 2)
Simplify the fraction
