Explain how a number line can be used to find de difference for 34-28

You need to put 34-28 to get your answer

If you subtract 38-24 then u get 14 which means jump back 14 units to the right if 24 is on the right to get there from 38 which is on the left of the number line, or jump 14 units to the left from 24 to get to 38 

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
