NEED HELP ASAP!! Which system of equations is represented by this graph?

a y=-2/5x-4

y=-3x+2

b y=-2/5x+2

y=-3x-4

c y=-5/2x-4

y=-1/3x+2

d y=-5/2x+2

y=-1/3x-4

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no
