B is the correct answer
slope-intercept is in the form y = mx + b
So since you know that x^2-1 is equal to (x-1)(x+1),
you can figure that this factors to
(y^2-x^3)(y^2+x^3)
because you know how the difference of two squares formula, stated on the top line of this answer.

Answer:
2x + 5y = -5
Step-by-step explanation:
Since the new line is parallel to the given line 2x + 5y = 10, the equation of the new line has exactly the same form as does 2x + 5y = 10, except that the constant will be different.
Were we to solve this equation (in standard form) for y in slope-intercept form, we'd get:
5y = -2x + 10, or
-2x + 10
y = ----------------
5
or
y = (-2/5)x + 2
Writing out 2x + 5y = C, we substitute -5 for x and 1 for y, obtaining
2x + 5y = C => 2(-5) + 5(1) = -10 + 5 = -5. Therefore, C = -5 and the equation of the new line is
2x + 5y = -5
