Which of the following equations demonstrate the set of polynomials is not closed under the certain operation? A. Addition: (x2 + x) + (x + 1) = x2 + 2x+1
B. Multiplication: (x2 - 5x+3)(x - 5) - W - 10x2 +28x-15
C. Division: (x - 5x+3) - (x - 2) = x-3+ ---
D. Subtraction: (3x* + **)-(-2x*+x") = 5x*

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
