Answer: -1
Step-by-step explanation:
slope form is [tex]m = \frac{y^{2} - y^{1} }{x^{2} - x^{1} }.[/tex] M is the slope. x1 and y1 are coordinates of a point along the line. x2 and y2 are the coordinates of another point along the line.
So we need to substitute in the points you have. let's put in (1, -2) for x1 and y1, and (2, -3) in x2 and y2. it makes [tex]m = \frac{-3-(-2)}{2-1}[/tex]
Now all you have to do is solve the equation.
[tex]m = \frac{-3-(-2)}{2-1}[/tex]
[tex]m = \frac{-1}{1}[/tex]
m = -1
(btw the line's equation would be y = -x - 1)
