Using technology, we get

slope =    0.025451465
intercept =    51.84001665

Thus, the regression line is

y^ =    0.025451465   x   +   51.84001665

Thus, if y = 85,

x = (85 - 51.84001665)/0.025451465 = 1302 [ANSWER, OPTION 2]

OPTION 2 is the closest answer, maybe there was some round off errors in the previous parts here. Anyway, the other values are far off.
