We need to find the value of given expression using a number line.
Two numbers are -3 and -7.
Plot these two numbers on the number line.
Now, start form -7 and jump up to -3 on the number line and count the jumps, then the number of jumps is the answer.
From below figure it is clear that the number of jumps between -7 and -3 is 4.
Therefore, the value of given expression is 4.
