What is true about the completely simplified sum of the polynomials 3x?y2 - 2xy and -3x?y2 + 3x^y? O The sum is a trinomial with a degree of 5.
O The sum is a trinomial with a degree of 6.
O The sum is a binomial with a degree of 5.
The sum is a binomial with a degree of 6.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
