Answer:
2/3 (the first one)
Step-by-step explanation:
let's use
[tex]\frac{y2-y1}{x2-x1}[/tex]
plug in the numbers
[tex]\frac{9-3}{1-(-8)}[/tex]
which becomes
[tex]\frac{9-3}{1+8}[/tex]
then simplify to
[tex]\frac{6}{9}[/tex]
then can be simplified again to
[tex]\frac{2}{3}[/tex]
if you divide 6/9 by 3
so
m = 2/3
which is the first one
