1. Identify each of the following situations or equations as proportional or non-proportional and explain your reasoning. (a) The total cost of rent is determined by recording x months of rent at $1400 per month, plus a $150 application fee.

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.
