Linear Functions and Proportionality

For the equation: k=y/x, the variable k is called the...

• Constant, and it represents the constant rate of change or constant ratio between x and y

• Coefficient, and it represents the constant rate of change or constant ratio between x and y

• x factor, and it represents the constant rate of change or constant ratio between x and y

• y factor, and it represents the constant rate of change or constant ratio between x and y

Is this a linear function? explain.

• This is a linear function because it has a constant rate of change of 6

• This is not a linear function because it has a y-intercept of 2

• This is a linear function because it have a constant rate of change of 3

• This is a linear function because it's y-intercept is (0,2)
