Factor this by grouping. Group the first two terms together and then the second 2 terms together. The idea here is that, after grouping, what you can pull out in both groups is the same. Like this:

Now work on finding a common thing between the 2 groups:

See, what you have in common there now is the (x-9) that you can factor out:

And that is factored completely.
Answer:
y=3x+6
Step-by-step explanation:
Coordinate:(-1,3)
Slope: 3/1=3
Formula=y-y^1=m(x-x^1)
y-3=3(x--1)
y-3=3(x+1)
y-3=3x+3
+3 +3
y=3x+6
