Question

Can I please get some help

Answer 1

*feels extremely lazy*
I DON'T WANNA DO THIS ; A;

Answer 2

jk lol
Okay you know the point-slope formula right?

Answer 3

yes i do isnt it y=mx+b

Answer 4

Um... \(y=mx+b\) is the slope-intercept formula. :P

Answer 5

oopsie

Answer 6

Did they teach you this one?\[y-y_{1}=m(x-x_{1})\]

Answer 7

@pphalke ?

Answer 8

no i was never taught that lol

Answer 9

Well then... \(\text{your teachers suck}\). >B[

Answer 10

Mine didn't either untii like 2-3 weeks after the first problem that we needed the formula for. =_= lol

Answer 11

yea she taught the easy way i said it didnt seem right

Answer 12

what would i do for this problem

Answer 13

That was back in 8th grade though :P

For this? Well, the \((x_{1},y_{1})\) is a point that the line goes through. You're given an x-intercept (7,0), so \(x_{1}=7\) and \(y_{1}=0\)

Answer 14

So then you input those into the formula \(y-y_{1}=m(x-x_{1})\), which gets you \(y-0=2(x-7)\) as slope m=2.

Answer 15

After that you just simplify/distribute and you should get the \(y=mx+b\) equation :D

Answer 16

y-0=2x-14

Answer 17

You don't need the 0 since anything minus 0 is still the original value :P
But otherwise you got it right! \(\text{Congratulations!}\)

Answer 18

y=2x-14

Answer 19

Yes :D

Answer 20

and in standard form>

Answer 21

Oh... ew.

Answer 22

*runs away...


to google*


LOL

Answer 23

LOLL

Answer 24

that is 2x+14=0 ::P

Answer 25

Nuh, no it's not ; - ;

Answer 26

I think this \(\text{link}\) might help: http://www.mathwarehouse.com/algebra/linear_equation/point-slope-form-to-standard-form.php

Answer 27

@Directrix do u know standard form for the problem i got y=2x-14 for slope int

Answer 28

*meanwhile returns to frying brains over my Pre-Calculus studying*

Answer 29

; - ;

Answer 30

*close question and gets ready to finish*

Answer 31

y-y1 = m*(x - x1) where m is the slope and (x1, y1) is a point on the line.

In this problem, the slope is 2 and the point has coordinates (7, 0).

y - 0 = 2* ( x - 7)

y = 2x - 14 which is the equation of the line in slope-intercept form.

---------------

Standard Form: the standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers.

The task is to write this equation in the standard form: y = 2x - 14

y = 2x - 14

y - 2x = -14

-2x + y = -14

2x - y = 14 is the standard form for the equation.
