Answer:

a) slope / m = 3

b) y-intercept / b = 0

c) Proportional

Step-by-step explanation:

a)

( y1 - y2 ) / ( x1 - x2 )

( 6 - 12 ) / ( 2 - 4 )

( -6 ) / ( -2 )

6 / 2

3

b)

y = mx + b

6 = 3(2) + b

6 = 6 + b

0 = b

c)

Proportional is when it crosses origin ( 0, 0 ).

Not proportional is when it does not cross origin.

Hopefully this helps!

7y-12-3y+9=0 help please
nasty-shy [4]

Simplify. Combine like terms

7y - 3y = 4y

-12 + 9 = -3

----------------------------------------------------------------------------------------------------------------

4y - 3 = 0

Isolate the y. Note the equal sign. What you do to one side, you do to the other side. Do the opposite of PEMDAS.

4y - 3 (+3) = 0 (+3)

4y = 3

4y/4 = 3/4

y = 3/4

-----------------------------------------------------------------------------------------------------------------

y = 3/4 is your answer

-----------------------------------------------------------------------------------------------------------------

hope this helps
