Prompt

Based on a model, on day

1

of an

8

-day experiment, a lima bean plant had an estimated mass of

253

grams, and each day after day

1

of the experiment, the estimated mass of the plant decreased by

4

grams. Which equation represents this model, where

m

is the estimated mass, in grams, of the plant on day

x

of the experiment and

1 \leq x \leq 8

m = - 4 x + 245

m = - 4 x + 249

m = - 4 x + 253

m = - 4 x + 257
