Question

Mathematicias pls help me ples

Answer 1

This problem is relatively simple. Before we begin, it might be beneficial to imagine the graph as a vertical number line. Imagining it this way makes it easy to count the units between them and gives you the answer:
`$\boxed{4}$`.

Here's a slightly more advanced way to think about it:

The example question tells us to subtract the distance between the two points. The formula for this is
`\sqrt{\big{(}(x_(2)-x_(1))+(y_(2)-y_(1))\big{)}^2`, but for this question, let's say that it is
`\sqrt{(y_(2)-y_(1))^2`, or, to simplify it even more,
`$|y_(2)-y_(1)|$`. Now that we know the formula, we can substitute our y-values into the last formula and solve. Let's say that Point C is our first point and Point D is our second.

`\big(-8)-(-4)\big = \big-8+4\big = \big-4\big = \boxed{4}` , so
`$4\text{ units}$` is our answer.

Disclaimer: Neither of the last two formulas I provided is the actual formula, just a version of the Distance Formula that might be easier to understand. The first formula is the actual thing, but you will encounter this in math later in life, probably around 8th or 9th grade.
