1) in 2001, there were about 62.5 thousand golden retrievers registered in the united states. in 2002, the number was 56.1 thousand. which linear equation best represents this information?
(a) y = 6.4x + 2001
(b) y = -6.4x + 12868.9
(c) y = 6.4x - 12743.9
(d) y = -6.4x + 2002

Linear equation is y=ax+b
Its decreasing so u need - a
2001 and 2002 would be your x at liner equation so can't have them as b
so answer is B

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
