Aradio tower is located on a coordinate system measured in miles. the range of a signal in a particular direction is modeled by a quadratic function where the boundary of the signal starts at the vertex at (4, 2). it passes through the point (5, 4). a linear road connects points (–3, 7) and (8, 2). which system of equations can be used to determine whether the road intersects the boundary of the tower’s signal?
