Is y=4.2x + 3 proportional

Describe the possible echelon forms of the standard matrix for a linear transformation t where t: set of real numbers is onto.

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2

Ihonestly have no clue if it's each or none.
