Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). 2 lines are graphed in an x y plane. The first line rises through (negative 7, negative 11), (0, 3), and (4, 11). The second line rises through (negative 1, negative 9), (0, negative 5), and (4, 11). Region to the right of (4, 11) is shaded. The shaded region in the graph represents the solutions of this system of linear inequalities: y 4x + y ≤ x + Note: Use the symbols <, >, <=, and >= for inequality signs.
