Help!

[Emma Lou]

Anyone good at math?

 

[Varemia]

Sure, why not. I have math goodness.

 

[Phil]

I am absolutely terrible with Math. :(

 

[OneoftheLost]

Depends....Me an' calculus ain' so good.

 

[Ru the Boatswain]

What is the question? We can help.

I am good with math, but only up to Geometry, course i probably could figure it out

 

[Emma Lou]

Here is the problem:

Find the y-intercept of the line passing through (2,5) and having the slope 2/3

Whoever answers this correctly and then explains to me how they did it get my eternal love and a cookie.

 

[Phil]

No eternal love or cookie for me. I'm absolutely clueless on that stuff. Why we must learn it is beyond me...

 

[Green Ranger]

Isn't the y-intercept just (0,5), or am I thinking about something else? It's been a year since i did this stuff, so give me a break if i'm rusty.

Here is the problem:

Find the y-intercept of the line passing through (2,5) and having the slope 2/3

Whoever answers this correctly and then explains to me how they did it get my eternal love and a cookie.

y-y=m(x-x)

y-5=2/3(x-2)

y-5=2/3x-4/3

y=2/3x-4/3+5

y=2/3x+11/3

y-int=11/3

I think this works, others should verify. I used point slope form.

 

[Emma Lou]

The answer 11/3. The answer is in the back of the book, but I cannot figure out how to get 11/3.

Me thinks you find another point on the line where it crosses the y axis.

A good explanation. Do I get a cookie?

EDIT: read all 4 pages.

 

[Varemia]

y-y=m(x-x)

y-5=2/3(x-2)

y-5=2/3x-4/3

y=2/3x-4/3+5

y=2/3x+11/3

y-int=11/3

I did it already. Make sense? Do I get a cookie?

 

[Green Ranger]

Woah, i'm really out of practice.

Of course I only did basic maths, so this point slop crap and everything makes no sense to me either way.

 

[Emma Lou]

y-y=m(x-x)

y-5=2/3(x-2)

y-5=2/3x-4/3

y=2/3x-4/3+5

y=2/3x+11/3

y-int=11/3

Do you understand it though?

 

[Emma Lou]

Okay I have one more...it's harder!

Write the equation of the line through (2,3) and perpendicular to the like 5x + 3y = 22

 

[Emma Lou]

Do you understand it though?

Yeah, I thought I tried that already, but I must have done it on another problem

 

[Varemia]

<3

Yay! I <3 you too.

Figures I had to go pee.
I am amazing at this stuff. I figured you had a higher math than I did.
