Question

What is the x-intercept of the line given by the equation 2x+3y=12

Answer 1

3y=-2y+12
\[y=-\frac{ 2 }{ 3 }x+3\]

Answer 2

whats the x-intercept?

Answer 3

1?

Answer 4

no remember y=mx+b
y=-2/3x+3 x= x-intercept b=y-intercept

Answer 5

2x+3y=12

Divide by 12

\(\dfrac{x}{6} + \dfrac{y}{4} = 1\)

Rather staring at you in this, The Intercept Form!

Answer 6

Im so lost with this

Answer 7

when finding the intercepts you need to put it y=mx+b for y=-2/3x+4 what number is with x?

Answer 8

2

Answer 9

is the 2 alone?

Answer 10

-2

Answer 11

When finding the y-intercept, do that.
When finding both intercepts, simultaneously, use the Intercept Form.

Substitute y = 0 for the x-intercept.
Substitute x = 0 for the y-intercept.

Answer 12

\[y=\frac{ 2 }{ 3 }x+4\]

Answer 13

im doing it the wrong way my mistake im finding slope tkhunny is right

Answer 14

2x+3(0)=12
2x=12 whats 12 divided by 2

Answer 15

6

Answer 16

x=6

Answer 17

Remember this?

\(\dfrac{x}{6}+\dfrac{y}{4}=1\)

Check out that "6" under the "x".

Answer 18

looks pretty good

Answer 19

this would have been just as easy to leave it in the form it was, let y = 0, and solve for x

Answer 20

i.e. solve 2x=12

Answer 21

What is the y-intercept of the line given by the equation y=2x-9

Answer 22

2(0)-9
solve for that

Answer 23

for the equation \(y=mx+b\)

\((0,b)\) is the y-intercept

Answer 24

so y always equals 0?

Answer 25

x = 0

Answer 26

\((0,a)\) is the form of the y intercept
\((a,0)\) is the form of the x intercept

Answer 27

if you're looking for x interecept plug 0 in for y if you're looking for y intercept plug 0 in for x

Answer 28

the intercept is not a number though, its the ordered pair

Answer 29

y=18

Answer 30
