Select the correct answer. Rosa is working on the electrical wiring for a community theater. She creates a diagram of the conduits joining different areas of the
theater on a coordinate grid and uses the line y = - 4x + 3 to represent the conduit between the stage and the dressing room. The
conduit between the ticket window and the security office passes through the point (4,7) on the grid and is perpendicular to the
conduit between the stage and dressing room.
What is the equation of the line representing the conduit between the ticket window and the security office?
y =
E-5 + 8
y = -43 + 23
y = 40 - 9
y = + 6
