OpenStudy (phebe):

can u help me wit a question

OpenStudy (phebe):

Write an equation in slope-intercept, point-slope, or standard form for the line with the given information. Explain why you chose the form you used?

OpenStudy (phebe):

A: passes through (-1,4) and (-5,2)

OpenStudy (nikato):

which form do you want to do?

OpenStudy (phebe):

standard form

OpenStudy (thomas5267):

If I am you, I would use point-slope form. We have to find the point-slope form before finding the standard form (as far as I know). First of all, try to find the slope.

OpenStudy (phebe):

ok i'll udse point- slope form then

OpenStudy (phebe):

ok so how do i do this

OpenStudy (nikato):

do you know what the point slope form is?

OpenStudy (phebe):

1/2 is the slope

OpenStudy (phebe):

yea i think so

OpenStudy (phebe):

mid point is (-3,3)

OpenStudy (nikato):

\[y-y _{1}=m(x-x _{1})\]

OpenStudy (nikato):

you do not need the midpoint just plug in your slope for m and just one of the points

OpenStudy (phebe):

what point

OpenStudy (phebe):

can u show me

OpenStudy (thomas5267):

The two points that are given (i.e. (-1,4) or (-5,2)). Just pick one.

OpenStudy (phebe):

ok

OpenStudy (phebe):

can u plug it in for me i don't know how to solve it

OpenStudy (phebe):

@nikato

OpenStudy (thomas5267):

\[ y-y_1=m(x-x_1) \] Let say you pick the (-1,4) as the point. You know \(m=\dfrac{1}{2}\), \(y_1=4\) and \(x_1=-1\). Just make substitution and do it .

OpenStudy (nikato):

\[(y-4)=\frac{ 1 }{ 2 }(x+1)\] or \[y-2=\frac{ 1 }{ 2 }(x+5)\]

OpenStudy (nikato):

becuz ur points are written like this \[(x _{1},y _{1})\]

OpenStudy (phebe):

ok

OpenStudy (phebe):

thanx

OpenStudy (nikato):

no problem

OpenStudy (phebe):
