Answer:

The given point (x,-1) divides the line joining the points (-3,5) and (2,-5) in the ratio 3: 2, and the value of x is 0

Step-by-step explanation:

The section formula is

P=(\frac{m(x2)+n(x1)}{m+n}, \frac{m(y2)+n(y2)}{m+n} )

Let the point P(x,-1) divides the line joining the points A(-3,5) and B(2,-5) in the ratio

m: n, then using the section formula, we get

(x,-1)=(\frac{2m-3n}{m+n}, \frac{-5m+5n}{m+n} )

-1 =\frac{-5m+5n}{m+n}

- m - n = -5m + 5n

4m = 6n

m : n = 3 : 2

To find the value of x, consider

x = \frac{2m-3n}{m+n}

Put m = 3 and n = 2

x = \frac{2(3)-3(2)}{3+2}

x = 0

Therefore the point (x,-1) divides the line joining the points (-3,5) and (2,-5) in the ratio 3: 2, and the value of x is 0
