Your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph.

1.5x + 0.2y = 2.68 1.6x + 0.3y = 2.98 0 the lines are parallel. the lines overlap at all points. the lines intersect at (1.6,1.4). the lines intersect at (3.1,0.5). which statement describes the graph of the system of equations below
