What are the two missing output values for the function y = 2x - 4 when x = 4 and x = 5?

Back

For x = 4, y = 2(4) - 4 = 4; for x = 5, y = 2(5) - 4 = 6. The missing output values are 4 and 6.

What is the relationship between input and output in a linear function?

Back

In a linear function, the relationship between input and output is constant, meaning that the output changes at a constant rate as the input changes.
