Line segment EG is partitioned by point F in the ratio 1:1. Point E is at E (0, 4), and point F is at (1, 3). What are the coordinates of point G?

(2, 2)
(3, 1)
(4, 0)

Answer:

2,2

Step-by-step explanation:

I don't really know how to explain it, but if you plot E and F on a coordinate plane it would make more sense.

*Note that the ratio 1:1 is not the same as the fraction 1/1, rather, 1:1 = 1/2 so point F is like a midpoint of segment EG

The coordinates of point G is (2,2)

The coordinate points are given as:

  • [tex]E = (0,4)[/tex]
  • [tex]F = (1,3)[/tex]

The ratio is given as:

[tex]m : n = 1 : 1[/tex]

Given that the ratio is 1 : 1, it means that, point F is at the midpoint of line segment EG

So, we have:

[tex]F =0.5 \times (x_1 + x_2, y_1 + y_2)[/tex]

This gives

[tex](1,3) =0.5 \times (0 + x, 4+ y)[/tex]

[tex](1,3) =0.5 \times (x, 4+ y)[/tex]

Multiply both sides by 2

[tex](2,6) =(x, 4+ y)[/tex]

By comparison, we have:

[tex]x = 2[/tex]

[tex]4 + y = 6[/tex]

[tex]y =2[/tex]

Hence, the coordinates of point G is (2,2)
