Which statement best explains whether y = 2x − 3 is a linear function or a nonlinear function?
it is a linear function because the graph contains the points (0.-3), (1, -1), (2, 1), which are on a straight line
it is nonlinear function because the graph contains the points (0, -3, (1 -1), (2, 1) which are not a straight line
it is a linear function because the graph contains the points (-3, 0), (-1,1), (1, 2), which are ona straight line
it is a nonlinear function because the graph contains the points (-3, 0), (-1, 1), (1, 2), which are not a straight line
