Compare Point E and -1: Number Line Position Analysis

Q: How do I know what number point E represents?

Look directly below point E on the number line. You'll see it's positioned exactly above the mark labeled $ -1 $, so E represents the value -1.

Q: What if two points are at the same position?

If two points occupy the same position on a number line, they represent the same value and are therefore equal, regardless of their different letter names.

Q: Why does E equal -1 instead of being greater or less than?

Point E sits exactly on the -1 mark, not to the left or right of it. When two numbers occupy the same position on a number line, they must be equal.

Q: Could this be a trick question?

Not a trick! Simply read where point E is located on the number line. The diagram clearly shows E is positioned at -1, making the comparison straightforward.

Q: What if the points were close but not exactly aligned?

Always look carefully at the exact positioning. If a point is slightly left of a number, it's less than. Slightly right means greater than. Exactly aligned means equal.

Fill in the corresponding sign

$E?-1$

Step-by-step solution

Let's locate the letter on the number line and see which number represents it:

$E=-1$

We can see that it's the same number, therefore:

$-1=-1$

Final Answer

$=$

Key Points to Remember

Essential concepts to master this topic

Position Reading: Point E is located at -1 on the number line
Comparison Method: E = -1, so E ? -1 becomes -1 ? -1
Verification: Same positions on number line mean equal values: -1 = -1 ✓

Common Mistakes

Avoid these frequent errors

Assuming different letters mean different values
Don't think E ≠ -1 just because they look different = wrong comparison symbol! Letters are just labels for positions. Always read the actual number value where each point is located on the number line.
