It should be about 22.55.
Answer:
y = -3x + 6
Step-by-step explanation:
Equation of straight line is given by,
y = mx + b
m = slope of the line
b = y-intercept
From the graph attached,
m = 
= 
= -3
y intercept 'b' = 6
Therefore, equation of the line will be,
y = -3x + 6
multiply all numbers together:
3*6*4*3 = 216 combinations
