Given the statement:

Line segment AB has endpoints A(10, 4) and B(2, 8).

x1 = 10

x2 = 2

y1 = 4

y2 = 8

Find the coordinates of the point that divides the line segment directed from A to B in the ratio of 1:4.

Solution:

In order to find the coordinate of the point that divides the line segment, we simply need to use the midpoint formula.

Midpoint Formula:

Midpoint = ( x2 + x1 )/2, ( y2 + y1 )/2

Midpoint = ( 2 + 10 ) /2 , ( 4 + 8 )/2

Midpoint = 12/2, 12/2

Midpoint = 6, 6

Since the scale is 1:4, we multiply 6, in the y coordinate by 4.

Midpoint = (6, 24)

Final answer:

Midpoint = (6, 24)
