Question

Write an equation for the line that is parallel to the given line and passes through the given point.

y = 3x + 7; (2, 10)

anonymous · Answer

You know the slope, and you have a point

anonymous · Answer

Do you know point-slope form?

anonymous · Answer

$$y-_{y1}=m(x-_{x1})$$

anonymous · Answer

okay

anonymous · Answer

So all you have to do is plug in the y coordinate for y1 and the x coordinate for x1, and you already have the slope, so plug that in for m

anonymous · Answer

um? y - 10 = 7( x - 2)

anonymous · Answer

good!

anonymous · Answer

Did your teacher teach you point slope form yet?

anonymous · Answer

yes, but that wasnt a answer choice

anonymous · Answer

what are your choices? All i need to know is the type of form (standard, slope intercept)?

anonymous · Answer

A) y = 3x + 11
B) y = 3x + 4
C) y = -3x + 4
D) y = (-1/3)x + 4

anonymous · Answer

okay so it's slope intercept...

anonymous · Answer

What you can do is simplify point slope

anonymous · Answer

Im not understanding. Which one is the answer?

anonymous · Answer

y - 10 = 7( x - 2) 
What would you do first?

anonymous · Answer

to simplify the equation

anonymous · Answer

yes.

anonymous · Answer

All you need to do is simplify the point-slope, so distribute the 7

anonymous · Answer

Im confused...

anonymous · Answer

you should get y-10=7x-14

mrnood · Answer

your equation is not correc

the slope is 3  not 7

go backt to
y− y1 =m(x− x1 )

anonymous · Answer

oh i didnt notice that thanks mr nood xD

anonymous · Answer

He said it was correct?

anonymous · Answer

The point slope form equation is:
y - 10 = 3( x - 2)

anonymous · Answer

so to turn it into slope intercept first distribute the 3

anonymous · Answer

okay...

anonymous · Answer

you should get y - 10 = 3x - 6)

mrnood · Answer

let him do the work - he will learn more that way

anonymous · Answer

thats not a answer choice though.

anonymous · Answer

That is only one of the steps

anonymous · Answer

Im a girl...

anonymous · Answer

Do you know how to simplify equations?

mrnood · Answer

it is one of th echoices - you just need to recognise it

add 10 to each side...

anonymous · Answer

okay..

anonymous · Answer

Is is y = 3x + 4?

anonymous · Answer

yes

anonymous · Answer

@MrNood ?

anonymous · Answer

All you did was isolate y

anonymous · Answer

that is slope intercept form

anonymous · Answer

@MrNood left.

anonymous · Answer

um okay... hope its correct. Thanks

anonymous · Answer

It is correct, you can trust me.

anonymous · Answer

okay

anonymous · Answer

its B
