Complete the standard form of the equation that represents the quadratic relationship displayed above, where a, b, and c are rational numbers.

Consider the proof. given: segment ab is parallel to line de. prove: what is the missing statement in step 5?

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.
