Question

Find the y value for point L such that JL and KL form a 3:1 ratio.


2.5

-1

-0.5

2

Answer 1

Do you know about similar triangles?

Answer 2

First things first: use the distance formula to find the distance between J and K. That'd give you the length of JK.

Answer 3

i got \[\sqrt{5}\]

Answer 4

and then i found the square root = 2.2

Answer 5

@ParthKohli

Answer 6

how did you get \[\sqrt{5}\]

Answer 7

(4-4)^2 + (-2+4)^2
1+4
5

Answer 8

Eh?

Answer 9

ill draw it up for you

Answer 10

i used the distributive prop.

Answer 11

@jeremyggg Could you take the charge? I'm currently busy doing other things at the moment. Thanks.

Answer 12

i got the answer thanks guys!

Answer 13

-0.5

Answer 14

ahaha! ok! my drawing would have worked but it wasn't pretty! did you figure out why it wasn't \[\sqrt{5}\]

Answer 15

lol yess i crossed multiplied 3/4 x 6/1 = 18/4 = 4.5
4 - 4.5 = -0.5

Answer 16

heheh that is the simple way! but your way of getting the length of the line wasn't right. you would make a right triangle and then see how long each side was, then do pythag of a^2+b^2 = c^2! good job though!
