How do you find the y-intercept for point slope (y=mx+b)? Points given: (2000,1500) (2008,2250)

Question

ajprincess · Answer

y-intercept=b
First find m
$$m=\frac{y_2-y_1}{x_2-x_1}$$
$$m=\frac{2250-1500}{2008-2000}$$
Plug in the value of m in 
y=mx+b
to find b.
Here y=1500 and x=2000

@ashdash  does that make sense?

anonymous · Answer

Ok, I did the slope as shown and got 375 over 4 (375/4). Now i plug in 1500=375/4x + B and isolate/solve?

ajprincess · Answer

put 2000 in place of x in 1500=375/4x + B  and then solve for b.

@ashdash ...  @ajprincess is good help... like medal-deserving help, don't you think ;) ?

AMEN!

anonymous · Answer

Medals are nice, but helpers here really just want to see learning... @ashdash, you are doing it right :)

anonymous · Answer

In that case, I want to give you that best reward @ajprincess ! I just started this account last night and am trying to figure it out as I go. How do i give you a medal? ;)

anonymous · Answer

heh... since I brought it up, allow me...

anonymous · Answer

click the blue button labelled "Best Response" beside any one of @ajprincess's responses... that gives her the medal.

It's not like it's real gold or anything (unfortunately)... It's not worth anything other than a visible representation that the person is a good helper, but that helps other students see who seems to be respected for their help.
