Need help please and thank you

Answer:
y = -x - 1
Step-by-step explanation:
Slope (m) formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\\frac{-2-(-3)}{1-2}\\\\\frac{-2+3}{1-2}\\\\\frac{1}{-1}\\\\-1[/tex]
y = mx + b
y = -1x + b or y = -x + b
(1, -2)
y = -x + b
-2 = -1 + b
+1 +1
-1 = b
y = -x - 1
Hope this helps!
