Question

Find the ratio in which the segment joining the points (1,-3) and (4,5) is divided by x axis ?also find the coordinates of this point on x axis

Answer 1

Answer:

y coordinate is 0

coordinates of x, y is (x, 0)

x1,y1=1,-3

x2,y2=4,5

By section formula

X=mx2+nx1/m+n,

Y=my2+ny1/m+n

0=m4+(-3) n/m+n

0=4m-3n/m+n

0=4m-3n

4m=3n

m/n=3/4

Then,

X=3(4) +4(-3) /3+4

X=12-12/7

X=0/7

X=0

ANS:Ratio is 3:4

coordinate of (x, y) =(0, 0)
