So, lets go over the number line.

Any value to the left of 0 is negative,

Any value to the right of 0 is postive.

In this case we see both numbers are to the left of 0 so they are both negative numbers!

Now, we need to figure out which inequality shows the relationship between the plotted points on the number line. This might sound a bit confusing, but basically they are just asking:

Which number is greater or less than on the number line?

A easy way to remember which number is a lower value is:

Which one is further to the left of zero.

So in this case, we see that -8 is further from zero than -4.

This means -8 is less than -4.

Lets look at our answers to see which one says this.

D says:

4<-8

This isnt true! 4 is not less than -8! 4 isnt even on the number line!

However, if it was. It would be to the right of the 0, since 4 is postive.

C says:

-4<-8

This isnt true either! it says that -4 is less than -8. But -4 is greater than 8, since we see that -8 is farther from 0 on the number line!

B says:

-8>-4

This isnt true also!  If we rewrite this, we see that it is basically just C flipped: -8>-4 = -4<-8. Since C was incorrect, B must be incorrect too!

This only leaves A

When we look at A:

-8<-4

This is true, since it says -8 is less than -4. -8 Is further to the left of 0 than -4 is, so -8 is indeed less than -4.

Hope this helps!

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
