Question

In what ratio does y axis divide the line segment joining the points (-4‚7) and (3‚-7)

Answer 1

Given ;

• A(-4,7)
• B(3,-7)

given that y-axis divides the line in particular ratio

let the ratio be m:n

we know that for any point on the y-axis => x-coordinate = 0

Thus by using section formula;

• Thus by using section formula;x = (mx2 + nx1)/m+n

• 0 = 3m - 4n/m+n
• 0 = 3m - 4n
• 3m = 4n
• m/n = 4/3

Thus y-axis divides the line in the ratio m:n = 4:3
