Answer:
They are both functions, linear equations, and they both have a constant rate if that is what you are asking.
Explanation:
Constant rate is k in y=kx. For the equation on the left, 2 is the constant rate and for the equation on the right is 0.5. They are both linear equations because if you line them up on a graph, it will show a straight line. And for every input should give one output. Hope this helps! Have a great day!
