Lucy graphed the equations x 9 y = 5 and 4 x 15 y = negative 1 and saw that they intersected at the point (–4, 1) as shown. On a coordinate plane, 2 lines intersect at (negative 4, 1). What can Lucy conclude? (–4, 1) is a solution to the system of linear equations. (–1, 4) is a solution to the system of linear equations. (1, –4) is a solution to the system of linear equations. (4, –1) is a solution to the system of linear equations.
