Answer 1

Ax+By=C

Answer 2

Hi Chris I am still having strouble...

Answer 3

y = -1x/2 + 1
y -1 = -1x/2
2y -2 = -x
2y+x -2 = 0
8y + 4x -8 = 0

Answer 4

this looks weird
m=-1/2 and b=1 is that what we are looking at
y=mx+b

y=-1/2 *x+1
1/2 *x+y=1

x+2y=2

Answer 5

yeah, I got what myininaya got

Answer 6

Alright So the equation you use is y-y1=m(x-x1)

Answer 7

and we got what moneybird got just add 8 on both sides
and divide by 4 on both sides

Answer 8

i used y=mx+b as i stated above

Answer 9

no, the standard form is the Ax+By=c so the answer is x+2y=2

Answer 10

Thanks.

Answer 11

oh.. and yeah, you start with y=mx+b just like myinimaya said.

Answer 12

Haha, Ok Input in standard form the equation of the given line.The line with m = -3/8 and passing through (5, -4)

Answer 13

y=mx+b

Answer 14

no I think this is y-y1=m(x-x1)

Answer 15

yes, start with y=mx+b, plug in m, x, and y and solve for b.

Answer 16

-4=(-3/8)(5)+b

Answer 17

y-y1=m(x-x1) is the point-slope form. it's just another way to write the linear equation

Answer 18

\[y=mx+b \]
m is -3/8
\[y=\frac{-3}{8}x+b\]
we know a point on the line (5,-4) => x=5, y=-4
plug that in to figure out what b is
\[-4=\frac{-3}{8} (5)+b \]
\[-4+\frac{3}{8} \cdot 5=b\]
\[-4+\frac{15}{8}=b \]
\[\frac{-32+15}{8}=b\]
\[b=\frac{-17}{8}\]
so the equation is \[y=\frac{-3}{8}x+\frac{-17}{8}\]

Answer 19

-4=-15/8+b

Answer 20

-3x-17=y

Answer 21

In standard form??

Answer 22

3x+8y=-17

Answer 23

Oh yea sorry..

Answer 24

Input in standard form the equation of the given line.The line that passes through (-3, 5) and (-2, -6)

Here I first find the slope of the equation. Then, do I still use the y=mx+b or do I use the other one?

Answer 25

-33x-5y=?

Answer 26

I would find the slope, just like you say, then use one set of your coordinates in y=mx+b to find your b, then convert the y=mx+b form to standard form.

Answer 27

So
