Since these segments are all equal, that means we're going to divide this line into equal parts. So we need to find the midpoint of pq.

Solved by pluggable solver: To find midpoint of segment connecting two point

The Coordinates of mid point of a line segment joining two points can be calculated using following formulas.

X coordinate of mid point is

Y coordinate of mid point is

Hence, The mid point of segment joining two point (-3,4) and (9,-4) is (3,0)

So (3,0) is the midpoint of pq. This means the coordinates of m is (3,0) since its right in the middle. Now lets find the midpoint of the midpoint, or in other words, find the point thats a quarter of a way there.

Solved by pluggable solver: To find midpoint of segment connecting two point

The Coordinates of mid point of a line segment joining two points can be calculated using following formulas.

X coordinate of mid point is

Y coordinate of mid point is

Hence, The mid point of segment joining two point (-3,4) and (3,0) is (0,2)

So at the quarter mark we have the point k(0,2). Now lets find the midpoint between the middle and the end, which is q(9,-4)

Solved by pluggable solver: To find midpoint of segment connecting two point

The Coordinates of mid point of a line segment joining two points can be calculated using following formulas.

X coordinate of mid point is

Y coordinate of mid point is

Hence, The mid point of segment joining two point (3,0) and (9,-4) is (6,-2)

So the coordinates of n are (6,-2). So the coordinates are:
k=(0,2), m=(3,0), and n=(6,-2)
You can always graph these points and the segment to visually verify this.
