In a different plan for area codes, the first digit could be any number fromnbsp 2 throughnbsp 7, the second digit was eithernbsp 2 comma 3comma nbspornbsp 4, and the third digit could be any number exceptnbsp 4nbspnbsp or 8. With this plan, how many different area codes are possible?

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.
