Answer:
2:9 is the ratio
Step-by-step explanation:
Using section formula, if a point (x,y) divides the line joining the points (x1, y1) and (x2, y2) in the ratio m:n, then (x,y)=(mx2+nx1/m+n, my2+ny1/m+n)
Now, let the ratio be k:1
Substituting (x1, y1)=(2,−2) and (x2, y2)=(3,7) in the formula, we get (k(3)+1(2)/k+1, k(7)+1(−2)/k+1)=(3k+2/k+1, 7k−2/k+1)
Since 2x+y−4=0 divides the line at P, this point will lie on the
2(3k+2/k+1)+ (7k−2/k+1) −4=0
6k+4+7k−2−4k−4=0
9k=2
k= 9/2
Hence, the ratio is 2:9

Answer:
use the formula
!(ax1+by1+c))!/((√(a^2+b^2))):!(ax2+bx2+c)!/(√(a^2+b^2))
so answer is
|2*2-2-4|/√(4+1):|2*3+7-4|/√(4+1)
|4-6|:|13-4|
2:9
