Right this is pretty simple all you do is sub the points to the equation given.
So first try the first point (2,-1) in y=-3x+7
==> -1=-3(2)+7
==>-1=1 this is not equal therefore not the right points
Then try (1,10)
==>10=-3(1)+7
==>10=4 this is incorrect therefore not the right points
Next try (3,-2)
==>-2=-3(3)+7
==>-2=-2 this is equal therefore this is the coordinates to the linear equation.
Finally try the last points to make sure you are correct.
==> -8=-3(-5)+7
==>-8=22 this is incorrect also.
Therefore the only coordinates that satisfies the equation is (3,-2)

Answer:
Here are just three examples I came up with:
-9(2 + 3)
or
-3(6 + 9)
or
-(18 + 27)
Step-by-step explanation:
- To come up with these expressions, I found common factors between the numbers -18 and -27.
- Then, I factored the numbers with the common factor (the common number is the number outside of the parentheses.)
- When you distribute any of the expressions above, you will find they they can be simplified to -18 - 27, which is the same as -18 + (-27).
