Question

Which is an equation of given line in standard form?
A. -11x+6y=-13
B. -6x+11y=13
C. -6x+11y =-13
D. -6x+7y=-17

Answer 1

Line has (-4,-1) and (1 1/2,2)

Answer 2

First, find the slope by using the formula
\[m=\frac{y-y_1}{x-x_1}\]
Once you've got the slope, simply pick one of the given coordinates, say (-4,-1), and plug it into
\[(y-y_1)=m(x-x_1)\]
Where \(y_1\) is -1, and \(x_1\) is -4.

Answer 3

is it B

Answer 4

did you find the slop?

Answer 5

@ToxicWaste

Answer 6

It is B

Answer 7

sorry @DJBreezy but im not really good at math

Answer 8

kk

Answer 9

Do you still need help? @DJBreezy

Answer 10

yaahh

Answer 11

Okay! To find the slope we can use the equation about and subtract\[\frac{ 2--2 }{ 1.5--4 }\]

Answer 12

And when you solve that expression, what do you get? @DJBreezy

Answer 13

U get 0.72727272

Answer 14

@neonumbrella5115
Aren't the y-coordinates of the two points 2 and -1?
Check your numerator above.

Answer 15

My mistake! The real equation is \[\frac{ 2--1 }{1.5--4 }\]
Thanks!! @mathstudent55

Answer 16

No. Your numerator needed fixing, and you did.
Your denominator was correct. Now it's missing the - of -4.

Answer 17

Oh, you fixed it again. Now you're good.

Answer 18

@DJBreezy What do you get when you solve the now-correct equation? xp

Answer 19

0.54545454

Answer 20

Your number for the slope is correct, but leave it as a fraction.

Answer 21

Now we'll write the equation in slope intercept form. so y=mx+b
However, we don't know the b value yet so we will have to solve for that. First plug the slope we just found in for m, and then you will plug in the x and y values from one of the coordinates in the original equation.

Answer 22

3/1.9

Answer 23

\(m = \dfrac{ 2-(-1) }{1.5-(-4) } = \dfrac{3}{5.5} = \dfrac{6}{11}\)

The slope is 6/11.

Now use the equation of a line given by @.Sam. above.
Plug in the slope we found above, 6/11, and the coordinates -1 and -4.
That will give you the equation of the line.
Then you need to put it in standard form:

\(Ax + By = C\)
