1) The linear function f(x) contains the points (-10, -29) and (-2, 83).

If g(x) = 25x - 50, which statement is true?
A. The functions f(x) and g(x) both have positive slopes. <<<

B. The functions f(x) and g(x) both have negative slopes.

C. The function f(x) has a positive slope, and the function g(x) has a negative slope.

D. The function f(x) has a negative slope, and the function g(x) has a positive slope.

2) A population of caribou in a forest grows at a rate of 2% every year. If there are currently 237 caribou, which function represents the number of caribou in the forest in t years?
A. C(t) = 237(0.98)^t
B. C(t) = 237(1.02)^t <<<<
C. C(t) = (237)(1.02)^t
D. C(t) = 237(0.02)^t

slope = (83- -29) / (-2 - -10)
= 112/8 = 14
which is indeed positive :)
237 (1.02)^t is correct
