Let K = (−2, 1) and M = (3, 4). Find coordinates for the two points that divide segment KM into three congruent segments.

@agent0smith

OpenStudy (agent0smith):

Just divide the x distance by 3, and the y distance by 3. That'll make it easy to find the points.

OpenStudy (will.h):

Or how about we multiply both pointS by 1/3?

OpenStudy (calculusxy):

Do you mean to do x_2-x_1 to find the x distance and y-2 - y_1 to find the y distance?

OpenStudy (agent0smith):

^Yes.

OpenStudy (calculusxy):

ok

OpenStudy (calculusxy):

x distance = 5 y distance = 3

OpenStudy (agent0smith):

Then divide it by 3, and add it the x or y value. Then add it again for the next point.

OpenStudy (calculusxy):

(-1/3, 2) (1 1/3, 0) <- not so sure about this

OpenStudy (calculusxy):

Wait it's (1 1/3, 3)

OpenStudy (agent0smith):

Looks reasonable. A graph again would help confirm if it's reasonable.
