"FIND THE DISTANCE BETWEEN EACH PAIR OF POINTS"

Start with the given distance formula
where

is the first point

and

is the second point

Plug in , , ,

Evaluate to get -9. Evaluate to get -8.

Square each value

Add

So the distance approximates to

which rounds to
12.04

So the distance between (-6,-4) and (3,4) is approximately 12.04 units

"FIND THE MIDPOINT OF THE LINE SEGMENT JOINING THE POINTS"

In order to find the midpoint between the points (-6,-4) and (3,4), we need to average each corresponding coordinate. In other words, we need to add up the corresponding coordinates and divide the sum by 2.

So lets find the averages between the two points

To find

, average the x-coordinates between the two points

So the x-coordinate of the midpoint is -1.5 (i.e. x=-1.5)
-----------------------------------------------------------------------------------------------------------------

To find

, average the y-coordinates between the two points

So the y-coordinate of the midpoint is 0 (i.e. y=0)
-----------------------------------------------------------------------------------------------------------------
Answer:
Since the coordinates of the midpoint are x=-1.5, y=0, this means the midpoint is (-1.5,0)

Check:
Here is a graph to visually see the answer
Graph of the line segment with the endpoints (-6,-4) and (3,4) with the midpoint (-1.5,0)

We could visually verify our answer if we simply draw right triangles from each point like this:

Here we can see that the two triangles are congruent, so our answer is verified.
