Question

Write an equation in y intercept form of a line that passes through the points (-2,5)  and (4,7)

anonymous · Answer

You have to do this first to find the slope$$\frac{ y^2-y^1 }{ x^2-x^1} $$

anonymous · Answer

The slope is 2/9

anonymous · Answer

How did u get a 9?

anonymous · Answer

Oh wait nevermind, its 2/6 :)

anonymous · Answer

I think I got the answer but I'm not sure. Is it y=2/6x+17/3 ?

anonymous · Answer

ok thats better! :)

Next you have to find the equation  y=mx+b
First plug in the slope for m
Then plug in on of the points for x and y 
Which will make you be able to find b

anonymous · Answer

I did not get the answer you have

anonymous · Answer

I checked it again. Thats what  I really got

anonymous · Answer

I'm confident thats my answer

anonymous · Answer

Try this$$5=-\frac{ 2 }{ 6}(-2)+b$$

anonymous · Answer

The slope isnt -2/6 its 2/6

anonymous · Answer

Opps the negative is suppose to be there

anonymous · Answer

The negative IS suppose to be there? in the 2/6 ?

anonymous · Answer

This is what you  should use$$5=\frac{ 2 }{ 6 }(-2)+b$$

anonymous · Answer

Yeah, that's what I did. After, I got 5=2/6(-2)+b and then I added 2/3 to both side and got b=17/3

anonymous · Answer

Was my answer right?

anonymous · Answer

b should be$$5\frac{ 2 }{ 3 }$$ Oh i see what you did, You kept it as a mixed fraction, but yes thats right

anonymous · Answer

ah okay thanks:)
