Which ordered pairs are in the solution set of system of linear inequalities? y_> -1/2x, y< 1/2x+1

Plot the intercepts to graph the equation

I’m still confused on how to work the percentages

Which polynomial equation of least degree has -2, -2, 3, and 3 as four of its roots? (x + 2)(x - 3) = 0 (x - 2)-2(x + 3)3 = 0 (x-2 + 2)(x2- 3) = 0 (x + 2)2(x - 3)2 = 0
