No is divisible by 7 if n is divided by 2 3 4 5 the remainder is 1 what is the smallest value that n could b

What is the equation of the graph below? y=sec(x)-4

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.

I'm confused on this could anyone me and show me what i need to do to solve it.
