Slope = 5/8

--------------------------
Equation:
--------------------------
y = 5/8 x + b

--------------------------
Find y-intercept :
--------------------------
At (8, 2),
2 = 5/8 (8) + b
2 = 5 + b
b = 2 - 5
b = -3

--------------------------
Equation :
--------------------------
y = 5/8x - 3

-----------------------------------------------------------------
Answer: y = 5/8 x - 3
