Evaluate a+4 when a=7 but how do you do it doe?

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.

What function has a range {yly< 5}? question on picture above^

Which point-slope form equation represents a line that passes through (3,-2) with a slope of -4/5
