Ab is dilated by a scale factor of 3 to form a’b’. point o which lies on ab is the center of dilation. the slope of ab is 3. the smile of a’b’ is __ a’b’ __ through point o. !

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.
