Answer:

A

Explanation:

Equation of a line is: y = mx + b where m = slope b = y axis intercept

To find the slope between any two of the given points :

say 18, 100 and 27, 85

m = slope = (y1-y2) / (x1-x2) = (85-100) / ( 27-18) = -15/12 = -5/3

so now you have

y = - 5/3 x + b we still need to find the value of b

use any point to calculate b

say 15, 106

106 = - 5/3 (15) + b

b = ~ 131

the equation is then y = - 5/3 x + 131 closest to answer 'A'
