Explain what does the constant rate of change means in the context, (basically what is the meaning of a constant rateme. this is the only way that i can get from smart people.

Here the topic is "functions."  Roughly speaking, we have a box.  Input enters at one end and output exists at the other.  Now, if every input value x (such as 2) is doubled by the box, every output value is 2x:  (0,0), (1,2), (2,4), etc.

We call this "doubling" a "constant rate of change.

If you plot the points given, you'll see that they all are on a straight line.  That straight line has the slope 2:  y = 2x.  Again, 2 is the "constant rate of change" here.

If you drive at a steady 55 mph, you are covering 55 miles during every hour behind the wheel.  Again, 55 is a "constant rate of change."
