To calculate this expression, we first add the given points (3,71-4,81) and (-2,2) together:
(3,71) + (-2,2) = (3-2, 71+2) = (1,73)
Next, we add the result with the point (3,85):
(1,73) + (3,85) = (1+3, 73+85) = (4,158)
Finally, we divide this result by 77/15:
(4,158) ÷ (77/15) = (4,158) ÷ (77/15) = (4(15/77), 158(15/77)) = (60/77, 2370/77) or approximately (0.78, 30.78)
