What number is represented by each of the letters on the number lines below?

Count the number of marks from one given number to the next.

There are four marks from 0 to 12. How much does each mark represent?

If four sections represent a total of 12, then each unit must represent 3.

Use the knowledge that the marks are made every 3 integers to determine what A, B, and C represent.

D represents −350. Why does that make sense? Now use that to figure out the values of the other points.
