A trail in a local park is 2 3/4 miles long. Mia walked the whole trail and half of the way back before taking a break for lunch. If T is the total number of miles Mia walked before her lunch break, write an equation to represent the distance Mia has walked.

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.
