Question

What integer does the letter B represent on the number line above?

Answer 1

-38

Step-by-step explanation

We are given the number line showing negative numbers.

We know that on the number line, as we move to the right, the number increases.

That is:

We see that the grading of the number line is 1, that is, each consecutive mark is separated by 1 unit.

B is 4 marks far from -42.

This means that we simply have to add 4 to -42 to get B.

So:

B = -42 + 4

B = -38

B represents -38 on the number line.
