Which of the following lines has x-intercept and y-intercept that are integers W? Choose the correct choice from the following answers:
A) y=3x+1	B) y=√x+1	C) y=-2/x	D) y=x^2-1	E) xy=1
Values that satisfy y=x^2-1 are (x,y)=(-1,0),(1,0),(0,-1). Hence, they are all integers W and the correct answer is y=x^2-1.
