The correct option is C 5-7Let the ratio be m-1-Then- the y co-ordinate of the point -m-7-1-x2212-5-m-1-x21D2-m-7-1-x2212-5-m-1-0-x21D2-m-57 - -x2235-y-0-Hence- m-1-5-7Option C is true

The line $y = 0$ divides the line joining the points $(3, - 5)$ and $(- 4, 7)$ in the ratio:
$3 : 4$
$4 : 5$
$5 : 7$
$7 : 9$

The correct option is C $5 : 7$
Let the ratio be m:1.
Then, the y co-ordinate of the point $= \frac{m (7) + 1 (- 5)}{m + 1}$
$\Rightarrow \frac{m (7) + 1 (- 5)}{m + 1} = 0 \Rightarrow m = \frac{5}{7}$ .... $[∵ y = 0]$
Hence, $m : 1 = 5 : 7$
Option C is true

The line y=0 divides the line joining the points (3,−5) and (−4,7) in the ratio:3:44:55:77:9

The correct option is C 5:7Let the ratio be m:1.Then, the y co-ordinate of the point =m(7)+1(−5)m+1⇒m(7)+1(−5)m+1=0⇒m=57 .... [∵y=0]Hence, m:1=5:7Option C is true

The line $y = 0$ divides the line joining the points $(3, - 5)$ and $(- 4, 7)$ in the ratio:
$3 : 4$
$4 : 5$
$5 : 7$
$7 : 9$

The correct option is C $5 : 7$
Let the ratio be m:1.
Then, the y co-ordinate of the point $= \frac{m (7) + 1 (- 5)}{m + 1}$
$\Rightarrow \frac{m (7) + 1 (- 5)}{m + 1} = 0 \Rightarrow m = \frac{5}{7}$ .... $[∵ y = 0]$
Hence, $m : 1 = 5 : 7$
Option C is true
