Answer:
18x - 9
Step-by-step explanation:
Factor the common factor of 9 first which gives 
is the difference of two squares and factors into (2x + 1)(2x - 1)
The complete factorization of 
is 9(2x + 1)(2x - 1).
So 9(2x - 1) = 18x - 9 is a factor of the original expression.
Answer:
y=x+1
Step-by-step explanation:
The slope intercept form of a line is y=mx+b, where m is the slope of the line and b is the y intercept. Since the line rises one unit for every one unit it moves to the right, it has a slope of 1. Since it intersects the y axis at the point (0,1), it has a y intercept of 1. Therefore, the equation is y=x+1. Hope this helps!
