Answer: x-5y+6
Step-by-step explanation: combine like terms
4x+2x-5x=x
2y-7y=-5y
8-2=6
Answer:

Step-by-step explanation:
We will use the equation of change in y over change in x to solve for the slope of the line. Then, we will simplify.




The answer is x(2x +5) (x + 6)
I would say that you cannot answer the question if you dont know either the X-value or Y-value. You need to know at least one of them to figure out the other.
