Which is the equation of a trend line that passes through the points open paren 7 comma 450 close paren and open paren 14 comma 401 close paren ?

The slope through the points is (401 − 450) ÷ (14 − 7) = −49 ÷ 7 = −7. Substituting (7, 450) into y = −7x + b gives 450 = −49 + b, so b = 499. Therefore, the equation is y = −7x + 499, choice A.
