Answer:

The point of intersection is (\frac{17}{8},0).

Step-by-step explanation:

Let the line segment joining the point (1,-3) and (4,5) is divided by x axis is k:1 and the point of intersection be (x,0).

Section formula,

P(x,y)=(\frac{mx_2+nx_1}{m+n}, \frac{my_2+ny_1}{m+n})

Using section formula, we get

\frac{my_2+ny_1}{m+n}=0

\frac{k(5)+1(-3)}{k+1}=0

5k-3=0

k=\frac{3}{5}

The x-axis divides the line segment joining the point (1,-3) and (4,5) is 3:5.

Using section formula, we get

\frac{mx_2+nx_1}{m+n}=\frac{3(4)+5(1)}{3+5}=\frac{17}{8}

Therefore the point of intersection is (\frac{17}{8},0).
