Can you tell me the answer please, i’d appreciate it sm. thanks

Yeah... I think u got it right... sorry if I’m wrong

Step-by-step explanation:

Explanation:

The length of segment MN is the same as the distance from M to N

Count out the spaces from M to N to see that there are 5 spaces, so that's why choice A is the answer.

Or you can break it down like this:

So we have 3+2 = 5 spaces total between M and N.

A more formal approach:

Let M = -3 and N = 2

Now subtract and apply absolute value.

|M - N| = |-3-2| = |-5| = 5

or

|N - M| = |2-(-3)| = |2+3| = |5| = 5

Either way, we get a distance of 5 units.

Absolute value is used to ensure that the result is never negative.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
