use the point given in y=1/3 x +b to solve for b.

Now you have the equation

**Bosnian**, Friday, May 25, 2012 at 7:17pmEquations of a straight line :

y = m x + b

Where :

m = slope

b = the y intercept ( where the line crosses the y axis )

Parallel lines have the same slope.

In this case m = 1 / 3

y = ( 1 / 3 ) x + b

x = - 9

y = 5

5 = ( 1 / 3 ) ( - 9 ) + b

5 = - 3 + b Add 3 to both sides

5 + 3 = - 3 + b + 3

8 = b

b = 8

y = m x + b

y = ( 1 / 3 ) x + 8
