First, we can use the slope formula to find the slope with the two points given:

m=(y2-y1)/(x2-x1)
m=(9-5)/(216.5-130.5)
m=4/86
m=2/43

Now, we can use the point slope form to find the equation of the line:

(y-y1)=m(x-x1)  *we can use either of the two points given*
(y-5)=(2/43)(x-130.5)
y-5=(2/43)x - 261/43
y=(2/43)x - 261/43 + 215/43
y=(2/43)x - 46/43
