B will b the answer that's the only answer yuh can get is b
Iam sorry i cant see the qusetion
(x-9) (x+2)=x²+2x-9x-18=x²-7x-18
i think maybe ? x+20*2=5-2*x
Parallel lines must have the same slope. However for them to be UNIQUE lines, ie different lines, they must have a different y-intercept.
So if we say generally that a line is y=mx+b where m is the slope and b is the y-intercept then these two unique parallel lines would be:
y1=mx+h and y2=mx+k
Where m is the same for both and each have unique constants h and k where they cross the y-axis
