Use the table of values to explain if d and y are proportional relationship

Math it's appreciated. (picture provided)

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.

Can someone show me step by step how to do this?
