Which of these equations represents a line that has an undefined slope and is perpendicular to the line represented by =5

We just started the introduction into circles and i have no idea how to do this.

On a piece of paper, graph y< x-1. then determine which answer choicematches the graph you drew.13. z3. 2(3.290-1)

36x2 + 49y2 = 1,764 the foci are located at: (-√13, 0) and (√13,0) (0, -√13) and (0,√13) (-1, 0) and (1, 0)edit: the answer is (- the square root of 13, 0) and (the square root of 13, 0)
