Points x and z are on a number line, and point y partitions xz into two parts so that the ratio of the length of xy to the length of yz is 5: 7. the coordinate of x is 1.3, and the coordinate of y is 3.8. what is the coordinate of z?

The coordinate of Z is (4.43, 11.57)

The coordinate of X is (1, 3)

The coordinate of Y is (3, 8)

Let the coordinate of z be (x₂, y₂)

The ratio of division is 5:7

m = 5, and n = 7

Let the coordinate of y be (a, b)

a = 3, b = 8

The coordinate of Z is (4.43, 11.57)
