Proportional Relationship and Additive Relationship

Given the table of values for the proportional relationship, what is the equation of the line in y=mx form?

• y = (1/2)x

• y = 3x

• y = -2x

• y = 2x

Given the table of values for the additive relationship, what is the equation of the line in y=x+b form?

• y = x -4

• y = x - 2
