Question

State the slope and the y-intercept for the graph of the equation.

3x + 6y = -6

Answer 1

If you can arrange it in this form:
y=mx+b,

m is the slope
b is the y-intercept

Answer 2

don't I have to get the y by itself?

Answer 3

Yes you have to

Answer 4

\[y = \frac{ 1 }{ 2 } (-x-2)\]

Answer 5

wait whats the work for it? Do I subtract it like this:

3x + 6y = -6
=3x =3x

Answer 6

m=-1/2
b=-1
m=slope b=y-int

Answer 7

\[3x + 6y = -6\]
Subtract 3x both sides
\[6y=-3x-6\]
Divide 6 both sides
\[y=-\frac{1}{2}x-1\]
------------------------
m is -1/2
b is -1

Answer 8

thank you :) how do I graph it?

Answer 9

this?

Answer 10

?

Answer 11

Yes

Answer 12

how i did it was ok?

Answer 13

yay, thanks :) can you help me with the next problem?

Answer 14

If your plot includes negative values of x that'd be greater

Answer 15

Write an equation in slope-intercept form to represent the table values.

Answer 17

Equation construction
\(y-y_1=m(x-x_1)\)
We need a coordinate \((x_1,y_1)\) and slope, m.
---------------------------------------
To find slope
Take the coordinates \((x_1,y_1)\) and \((x_2,y_2)\)
Slope formula is
\[Slope=\frac{y_2-y_1}{x_2-x_1}\]
Substitute and find slope
---------------------------------------

Answer 18

can I choose any coordinates?

Answer 19

I got 7
