Question

Find the ratio in which the line segment joining A(– 5, 3)) and B(2, -4) is divided by the y-axis.

Answer 1

Answer:

5/2 : 1 is the ratio

Step-by-step explanation:

let the ratio be k:1

line divided by y axis it means X=0

so point of intersection is (0,y)

then we'll fine the ratio

take any point ( X or y ) to find th ratio

0 = 2k - 5/k+1

2k-5=0

k=5/2 , k:1= 5/2:1

if y is to be found

then

Y = -4k+3/k+1

out the value of k in it

Y = -4×5/2 + 3 ÷ 5/2 +1

Y = -10 +3 ÷ 7/2

Y= -7/7/2 = -7/1 ÷ 7/2

Y= -2
