Question

If the slope of a line is 5/3 and it passes through points (6,4) and (x,8) what is the value of x... The answer is 42/5 ( I only know that cuz my summer assignment answer sheet told me) but I have to show detailed work and I don't know what to do!! Please help me!!!

Answer 1

do you know how to find the equation of line?

Answer 2

I think so.... Is that the x-x1 or something... Don't make fun of me if its not, it's just a guess:)

Answer 3

yup something like that.. you can find the equation of line by this formula

y-y1= m (x-x1)

u have the slope.. and point (6,4)

Answer 4

Wait, and stay with me here, does that help. So I think this is where I'm supposed to do this:

5-3
-------
6-4
Is this right?

Answer 5

Ummm no O.o
you have the slope.. m = 5/3 and point (6,4)

out these values in the equation i wrote in the previous comment.

Answer 6

Oh sorry... Okay did that

Answer 7

so what is the equation you got?

Answer 8

Is it 6-4= 5-3? If not I'm not being stupid on purpose

Answer 9

y-4 = 5/3 (x -6)

now try solving it

Answer 10

Can someone please help me? I'm desperate!!!,:)
