Answer:

y = 4/5 x - 2 1/5

Step-by-step explanation:

1.  Find the slope:

   1 - 5  =   -4    = 4  = m

   4 - 9       -5        5

2.  Find b by plugging in the slope you just found and one of the points given into y = mx + b

1 = 4/5 ( 4) + b

1 = 16/5 + b

- 2 1/5 = b

3. Plug in the m and the b you found into y = mx + b

y = 4/5 x - 2 1/5
