Answer:
[tex]y=-\frac{1}{3}x -8[/tex]
Step-by-step explanation:
1) Write down the standard form of an equation of a line and the formula to find m.
[tex]y=mx+b[/tex]
[tex]m=\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
2) Find m using the formula then substitute it into [tex]y=mx+b[/tex].
[tex]m=\frac{-5 - (-6) }{-9 - (-6)}\\m=\frac{-5 +6 }{-9 +6}\\m=\frac{1}{-3} \\m=-\frac{1}{3}[/tex]
So, [tex]y=-\frac{1}{3}x +b[/tex].
3) Find b by substituting a pair of coordinates the line goes through.
[tex]-6=-\frac{1}{3}(-6) +b\\-6=2+b\\-6 - 2=b\\-8=b[/tex]
4) Substitute b into [tex]y=-\frac{1}{3}x +b[/tex] to get your final answer.
[tex]y=-\frac{1}{3}x -8[/tex]
