Y=mx + b
3x-4y=12
4y=3x-12
y=3/4x-3
when x = 0, y = -3
when y = 0, x = 4
Hope this helps.

Answer:
105
Step-by-step explanation:
15x=7x+6+7x+1
15x=14x+7
x=7
15(7)=105
Given:
y varies directly with x,
It is given that y = 7 when x = -9.
To find:
The value of y when x = 27 for the direct variation.
Solution:
It is given that y varies directly with x, so
...(i)
Where, k is the constant of proportionality.
It is given that y = 7 when x = -9. Putting these values in (i), we get
Putting 
in (i), we get
Putting 
, we get
Therefore, the required value is .
