An air show is scheduled for an airport located on a coordinate system measured in miles. the air traffic controllers have closed the airspace, modeled by a quadratic equation, to non-air show traffic. the boundary of the closed airspace starts at the vertex at (10, 6) and passes through the point (12, 7). a commuter jet has filed a flight plan that takes it along a linear path from (–18, 14) to (16, –13). which system of equations can be used to determine whether the commuter jet’s flight path intersects the closed airspace?
