Given b = {a, l, g, e, b, r} and c = {m, y, t, h}, find b ∪ c. {} {a} {a, b, e, g, h, l, m, r, t, y}

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.
