Match the positions on the number line with the numbers they represent. -2.2 1.8 2.2 -1.8

Ineed i been stuck on this question since yesterday

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.

Which of the following can be used to explain a statement in a geometric proof?
