Point X is located at (-2, -4) and point Y at (1, -1). If line segment XY is rotated 90 degrees counter-clockwise about point X. What is the relationship between the slopes of line segment XY and line segment X'Y'? They are parallel because their slopes are the same.

They are parallel because their slopes are opposite reciprocals of each other.

They are perpendicular because their slopes are the same.

They are perpendicular because their slopes are opposite reciprocals of each other.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
