Select all the expressions thay could represent the volume of a box, which is a 3rd degree polynomial in variables x and y A. 2y-xy³+7
B. 3x²y+5xy
C. 3y³+3x³y⁴
D. 3xy-3xy²
E.3x³y²-3x²y+10y²-10y

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!
