Question

If the linear equation 2x = 9 − 3y is written in standard form, what is the value of B?

Answer 1

well standard form is Ax+By=C
so u want to first get it in that form

Answer 2

so can you write your equation u have for me in standard form?

Answer 3

sure

Answer 4

2x+3y=9

Answer 5

wait i didnt change the signs...

Answer 6

yes u did its correct

Answer 7

oh my bad thank you

Answer 8

so the value of b would be 3? Because i think there is more.

Answer 9

haha its fine:) so u want to find B. well B is the y intercept. so can u tell me what the y intercept in this equation?

Answer 10

oh ok

Answer 11

i meant 3 soorry

Answer 12

the y intercept is not 3

Answer 13

would the y intercept be 3 because its paired with b?

Answer 14

no

Answer 15

lets start from here:
y=mx + b
can u tell me which form this equation is written in?^

Answer 16

slope intercept form

Answer 17

correct! and can u tell me what each variable stands for?

Answer 18

so the slope stands for mx right?

Answer 19

but the slope is what we are trying to find.

Answer 20

im so confused right now

Answer 21

woah there! look... this is what the variables stand for..
m=slope
b=y intercept
y= what u solved for
x= intercept

Answer 22

ok ya i remember

Answer 23

notice that in the equation of slope intercept form..
y=mx+b
b has no variable connected with it.

Answer 24

so in your equation.. 2x+3y=9
which number has no variable connected to it?

Answer 25

ok

Answer 26

9

Answer 27

correct!!

Answer 28

so what would the answer be?

Answer 29

9 because it is in place of the letter b

Answer 30

thank you :)

Answer 31

no problemo:)
